Week 10 Blog, Due Sunday, November 3rd by 11:00 pm
This week we finally used our mousetrap cars in our lab practicum. The purpose of the lab practicum was to prove whether or not your mousetrap car had uniform acceleration. Some of you discovered that your cars did not travel in a straight line and that made data collection more difficult. Some of you had cars that barely went 1 meter. For this weeks blog, I want you to reflect on the construction of your car, the ability to collect good data for the analysis, and the actual motion of your car (uniform acceleration and non-uniform acceleration). How successful was your car and experiment? What difficulties did you encounter? What would you do differently if you had a chance to do it over? Or any other aspect you want to discuss. Remember, keep it friendly and avoid texting language. In order to receive full credit you must post an original comment plus reply to one other person's comment.

My car wasn't as succesful as others, but I was satisfied because it traveled further than I expected. I had trouble trying to make the car go because my string kept getting stuck. If I could do my car again, I would use something different for axles because that's what I think prevented the car from moving faster.
ReplyDeleteI think that is one of the most probable causes of he wheels not turning correctly
DeleteMy car was not as successful as others. I was satisfied with the turnout but not so much with the fact that the car did not go. for future reference I would use something different as the wheels.
ReplyDeleteI think your wheels were the problem. I'm still amazed of how you built it from everyday households and how you made your wheels from scratch!
DeleteWheels were the biggest problem that most people had.
DeleteIf the wheels were heavy and thick the cars wouldn't move.
Deletei agree with Lourdes haha it does amaze me that u built it so homemade and it went!
DeleteI thought my car was pretty good when I tested it at my house, however, at school I'm not sure what happened, but it wouldn't reach 5 meters. I think I would try organizing the car itself better. I would make sure the wheels are parallel to each other so it wont wobble, but I think I would still keep the same structure of it. I wasn't really satisfied at the end because my string broke. Hence, my car was not successful.
ReplyDeleteYour car looked nice and it looked like it would work well.
DeleteSame thing happened to me, it seemed to travel less at school than at home.
DeleteMy car was different than others because mine & Gabriel's car kept taking a hard turn to the left. It traveled far & was pretty fast, but it kept turning. If I could redo our car, I think we'd use different wheels and use a shorter string.
ReplyDeleteThat's nice that your car was fast. :-) or car kept going to the right and hitting the desk so don't feel too bad!
DeleteMine was turning to the left too but sadly it didn't go fast or far
DeleteYour car was pretty fast though.
DeleteMy car was successful, as well as my experiment. My car sort of gave up as we did several trials to try and calculate its velocity. If I were to make another mousetrap car, i would definitely take more time on my wheels to improve its overall performance.
ReplyDeleteThe only reason I liked your car is because it was made out of Versace. I think it went into the future when you tested it. Oh, but you should try some rubber textured tires.
DeleteThe car came out to be actually very cooperative when it came to traveling a distance of 5 meters. For the experiment I chose to use a friend's car (which was slower) to get more accurate data. Something happened to the car's tires, so the data kept changing. Meaning my data isn't as well as it should be. It'd be best to use a reasonable car next time. Overall, it was a fun assignment.
ReplyDeleteThat car was awesome
DeleteMy car did have uniform acceleration and it went to the right due to the wheels being aligned wrong. This made data collection harder. My car did go 5 meters but i had to face it a different way. If i had to do it over i would spend more time making the wheels straight.
ReplyDeleteMe too...My wheels were all wobbly and such.
DeleteI think your car worked well
DeleteBy the way you describe your car it doesnt sound too bad.
DeleteMy car went slow but I was happy that it reached the 5 meters. I could of used a longer stick with a longer rope to help it plus I would of added balloons on the front wheels too to add friction
ReplyDeleteI should of also added balloons to help the car move.
DeleteSame here, I needed a longer string.
DeleteMy car went SUPER SLOW like I spent a bunch of time building it and it went 5 meters successfully in my friend's garage but when we did it in class...it failed me miserably. I just don't know what went wrong. I think I should take some of the decor off it and add more balloons to the wheels.
ReplyDeleteThe same thing happen to me at first it work perfectly n them in class I don't know what happen :/.
DeleteWhen I tested my car at my house it seemed to travel the 5 meters but at school it didn't reach that distance. I'm thinking that the wheels probably starting getting wobbly and by the time I tested it in class they were no longer straight enough to travel long. Next time I guess I would make sure to spend more time on the wheels, everything else I was pleased with.
ReplyDeleteYea me 2 I would take more time in the wheels.
DeleteI had the same problem. My wheels were a bit wobbly when I tested the car.
DeleteThe car I constructed was decent, it just needed to move in a straight path. The wheels on the car were crooked, causing the car to go a different path. If i could do it over again, I would take more time and do the procedures precisely.
ReplyDeleteI had a similar problem with the wheels if they had been more flexible and sturdy it would have gone far.
DeleteWell my mousetrap didn't work that well I don't know what happenand. Well if I could do it again , I would take more time to do it.
ReplyDeleteYea I would take more time to do my mousetrap.
ReplyDeleteWhen I tested my car at home it went about 7 meters. In the morning at school I was racing with other cars, and I think that's why my car was not functioning well. The one thing I would change is to go slow because the car was to fast to calculate the data.
ReplyDeleteI liked the design
DeleteMy mousetrap car traveled past the 5 meters but drifted after we adjusted the wheels by adding cd's. The car traveled at a decent amount. The car was successful after we made that adjustment. If we had a second chance I would've done the same thing, the car met the standards for the lab practicum
ReplyDeleteIt would've probably gone farther if we didn't use so much glue
DeleteI think your car was pretty good overall. Good job!
DeleteDude that seems awesome brah!
DeleteMy car indeed had difficulties at not achieving the 5 meter mark. It traveled only 4 meters and a half but I believe that if the wheels were constructed more round then the care would have gone farther. Having that said the data collection would have been easier if the car would have gone a bit straighter.
ReplyDeleteMy car went the 5 meters. It was hard to collect data because my car wouldn't go straight. I probably would've gone straight if the axle here tighter and a bit heavier.
ReplyDeleteMy car went more then 5 meters but it didn't travel in a straight line, so it was very difficult to collect data. If I had a chance to do it over i would make my car sturdier in the middle because i used cardboard but very thin cardboard making it easy to bend. which is what happened and tried to make my car go straighter.
ReplyDeleteI had that exact same problem. i just glued another thin cardboard ontop of it.
DeleteAfter adding CDs my car was successful in surpassing 5 meters yet it curved. if the box hadn't torn or if the wheels actually were straight, the experiment would have gone better
ReplyDeleteYeah I think your car needed the Cd's because it did way better with them.
Deletemy car did not preform as well as I hoped it would, if I could start over I would put a lot more time into its construction.
ReplyDeletei agree with you i should have put more time into the car.
DeleteProcrastination kills xP
DeleteThe good thing is that you did it and that's what matter.
DeleteMy mousetrap car traveled a little more than 5 meters but it went slow and kind of curved. i would change my wheels so that they were straight. I'm not sure if my car had uniform acceleration because i wasn't at school the day it was tested. I need to stay after school to get it done.
ReplyDeleteMy car traveled the 5 meters, but it did not go straight which made it hard to calculate it. If i can do this project again i will take my time because I just rushed through it.
ReplyDeletemy car didnt meet my expectations maybe if i would have took my time it would have been much better
ReplyDeleteDue to being absent, I did not get to see the performance of my mouse trap car, although I had tested it before and my partner told me that it did meet the 5m distance, though it was a little shaky not going in a perfect straight line. However, I plan to stay after school and collect the data.
ReplyDeleteMine and my partner's car did not travel the 5m. This was because our design was not effective enough to do so. Therefore, we used our partners car to find uniform acceleration which was not present it did however travel the 5m. I wish we could have adjusted the string so it would not have broken.
ReplyDeleteOur car and experiment met our standards. The mousetrap car did reach 5 meters but did slightly turn toward the end wich made it a little difficult to collect data. If we had the chance yo do it over, my group wouldn't change nothing. Our car was pretty unique and aslong as it reached our goal then that's all that mattered.
ReplyDeleteMine and my partner's car did go 5m, and it was very successful. It met our standards, but sometimes we had trouble with the wheels. Overall, we really wouldn't change anything.
ReplyDeleteSame here on the first part, except my car wouldn't go straight
DeleteOur cart (Ariel's & I) did ran 5m,but not with a speed we expected.We had tested the cart at home & it went a longer distance with a greater speed.We probably messed around it too much.Maybe the speed would increase If we probably used fishing wire instead of string.
ReplyDeleteSounds great
DeleteAfter testing out my mousetrap car, I found that it did travel past the 5 m, but it did not have uniform acceleration. If I could change anything with the car, it would probably be the wheels. They weren't exactly aligned as straight as they could be, causing the car to wobble a bit.
ReplyDeleteMines too :/
DeleteMy car was successful, but the data was hard to collect because my car's wheels were wobbly causing it not travel straight. I would have aligned the wheels differently.
ReplyDeleteMAN MY CAR WAS ON POINT It WENT LIKE 500 METERS. IT HAD LIKE THE BEST UNIFORM ACCELERATION JUST THAT THE AXLE BROKE OFF ON THE 2ND WHICH WAS HILARIOUS. THE ASPECT I WANT TO DISCUSS IS WHY THE TEXANS LET THAT SUCKY KICKER KICK THE FIELD GOAL. >:/
ReplyDeleteEverything just got real with the CAPS LOCK on.
DeleteMy car was awesome man, it went over six meterss and tears slowly came out of my eyes. I wouldnt change anything, my car was perfect.
ReplyDeleteMy car went well. It traveled the 5 meters that it was supposed to travel. The only bad thing is that it didn't travel in a straight line. It had a curve to the left which made it not so great for me.
ReplyDeleteMy mousetrap car was perfect except for the fact that it went to the side and made a curve. I'm pretty sure it was due to the wheels because I didn't glue then directly in front of each other. If I hadn't done that, my car would have gone in a straight line and my lab practicum would have been easier.
ReplyDeleteatleast it was a good car
DeleteMy car went 5 meters and I was like oh wow I can't believe it but the difficult part was how to put the cd's in the car and if I could do it again I would ask for help there it goes
ReplyDeletesame here man
DeleteI think my car did alright because I met my goal. I think if I would of used lighter material it would of went faster and further maybe try to figure out how to create more friction.
ReplyDeletemy car wasnt that successful it had difficulties to go in a straight line and collect data,if i had do the experiment over again the car will be more acurate and the data will too
ReplyDeleteOur car didnt go as far as the 5 m at first and I was mad cus it took me hours to do it, but after it got fixed it even went more than 5m which was awsome!
ReplyDeletemy car wasn't successful, it sort of did a burnout then moved. it traveled at an angle and no matter how many times we tried it still didn't work the way we wanted. i think what we could have changed was the axles and what we used for wheels because they wouldn't stay straight.
ReplyDeleteMy car exceeded it's goal and had a different structure than most. The only thing I would have done different is aligned the wheels because they rolled wobbly but it still went pretty straight. It did not have uniform acceleration as it sped up the further along it went.
ReplyDeleteour car didn't go as we expected. our car barely met the 5 meter standard :(. we should've use our marterial more efficiently than we did.
