We started talking about projectiles in class this week. I would like you to look around you and think of some projectiles you see everyday. I want you to answer the following questions about your projectile:
What makes it a projectile? Is a horizontally launched projectile or a projectile launched at an angle? What type of range or height does you projectile have? Any other comments or observations you made about your projectile. If you have questions or problems posting, make sure you send me an email before 11:00 pm on the 21st. Remember, in order to get the full 100 points, you must make an original post PLUS comment on at least one other posts. Late posts will be given half credit. If you email me a your post, please use the physicswithego@gmail.com email address. Happy Posting!
A football getting kicked is an example of a vertical component. This projectile that is launched at an angle. Because it is being launched at an angle its trajectory forms a parabola. The height is determined by the formula Viyt+½gt².
ReplyDeleteApproximately what s the range? This is a perfect example of a projectile.
DeleteLile the example to use a kicked football
DeleteWhen I go swimming I like to dive from the diving board. That is an example of a Horizontally Launched Projectile. The height of the is how high the diving board is from the level of the water.The formula for this type of projectile would be deltaY= Viyt+1/2gt2
ReplyDeleteI like how you used swimming it really makes sense, very good projectile.
DeleteYour example was very good but the formula for this type of projectile is delta Y=1/2gt^2.
DeleteOther than the mistake on the formula, this is an original & great example. :)
DeleteEveryday when i am at basketball practice i am shooting a a vertical projectile. When the ball releases from my hand it must rotate and have a big arc when shooting so that way the ball goes in easily. It makes a U shape, a parabola and goes pretty high up. The only way to determine the height or range of the shot is to use the formula Viyt+1/2gt².
ReplyDeletethis is a different form of vertical projectile. because of the examples of vertical projectiles we don't think that it can go upwards, but this is a good example
DeleteGreat example Crystal! I like way you compared it to Basketball and your an Awesome Basketball Player! :)
DeleteIf you think about it, it really is a good projectile because it falls through the hoop similar to falling off a cliff.
Deletewhen you see a golf ball being hit it is starting at ground level, but once it comes in contact with the club it takes off at an angled projection then comes back down. the height and distance depend on the skill of the player.
ReplyDeletegood example
Deletegood example
Deleteusing golf is a good example of an angle projection
Deletewhen you throw a baseball it is a horizontally launched projectile
ReplyDeleteThat's a good example, but what would be the starting height for it?
DeleteThat's partially true, to go farther out, wouldn't you throw it at an angle?
DeleteIt would be if it was a curveball that went straight into the dirt
DeleteWhen you do a goal kick in soccer the projectile is launched at an angle.The hieght it found by viy+1/2gt and the distance by vx(t)
ReplyDeletegood example and smart you know your formulas (:
DeleteThat's a good example because it true lol :))
DeleteAn example of a projectile is a toy car driving off an incomplete bridge it's launched horizontally about 3ft. off the ground and if you want to know how high you use X=Vxt.
ReplyDeleteA arrow being shot is a exsample of a projectile. It is launched at a angle,so it is a vertical component. To find the hight we would use Viy+1/2gt2.
ReplyDeleteI agree and arrow being shot is a good example.
DeleteEverytime I shoot my slingshot I create an example of a horizontally launched projectile. My height represents the delta Y
ReplyDeletewhich you can find using the following formula delta Y=1/2gt^2. In the otherhand you can use the x=Vxt formula to find how far the object that was shot traveled.
good use of explaining how each formula fits in to the example.
DeleteGustavo you would have a slingshot! lol i have one too(: its a great example
DeleteA dart is an example of a projectile. it is launched at an angle and the height can be found using
ReplyDeletedelta V=1/2gt^2.
Very creative example. I like that formula too.
DeleteI didn't even think of that :o
DeleteIf you have a ball stuck on the roof and you throw it back down, this is an example of horizantally launched projectile. the hieght of the house would be your y component.
ReplyDeleteA ball this projectile is launched with an initial horizontal velocity from an elevated position could be ana example.
Deletei like your example! What was the approximate range though?
DeleteAna Mendoza
In a Soccer Game when the goalie gets the ball they sometimes kick it to the other side of the field. That's an example of a vertical component. This projectile that is launched at an angle, which then forms a Parabola. The height is determined by the formula Viyt+½gt².
ReplyDeleteShooting a gun fires a projectile. It is a horizontally launched. Usually has a range of 1000 meters and has a height of which you fire it at.
ReplyDeletethats a good example of a projectile
Deletewhen you watch a pitcher throw a baseball, its just like the catapult you have to release at a certain point in order for the ball to get where you want it hit. if you release late its going straight towards the ground and if you release early its to go up in the air but if you release right its going straight for its intended target. the ball is launched horizontally.
ReplyDeleteKick ball is an ex. Of a projectile because they trow the ball and the person kicks it at an angle
ReplyDeleteWhen hitting a ball with a bat it doesn't really have a specific projectile it can go either horizontally or vertically because for example it can be hit directly to 2nd base or it can be a pop-fly which makes a parabola, just like when the St. Louis Cardinals play!
ReplyDeleteGood example Leste! :)
DeleteWell I'm sure you guys remember that cartoon show about the road runner and the coyote always chasing after it. Well, in this one episode, the road runner runs towards a cliff and the coyote is chasing it. However, the road runner stops at the edge before he can fall and the coyote ends up falling. This would be an example of a horizontal projectile. The height of the cliff being deltaY and how far the coyote landed from the cliff (range) being deltaX.
ReplyDeleteI miss that cartoon. Back then those kind of cartoons were funny.
DeleteI love that show great example!
DeleteI used to love that show when i was young. Nice example!!!
DeleteThats a very creative example, & i loved that show too(:
DeleteAn apple falling sown a tree is an example of horizontally lauched. Everyone else took some good ones or just kinda used the same thing. Oh well we all just getting a grade for this.
ReplyDeleteHernandez at least make it sound smart
DeleteThat is a good example. So how far did the apple fall from the tree?
DeleteWhen you kick a ball to make a goal you are creating a projectile. The ball is thrown and it travels horizontally at an angle.
ReplyDeleteit can also be a vertical projectile when the ball is just getting tip
DeleteOur catapults were perfect examples of an vertical projectiles because they were launched at an angle and formed parabolas
ReplyDeleteOn the game red beard everytime i jumped wrong the Little man with the red beard would fall off a cliff into water filled with spikes. Thats an example of a horizontal projectile. Delta y would be the cliff to the spikey water and the range. Would be how far.
ReplyDeleteI have never heard of this game tokyo! It sounds funny though and good example with the cliff!
DeleteA projectile is an object upon which the only force acting is gravity.hieght of this trajectory is determined by the parabola. for example a soccer ball being kicked across the feild. this is a vertical projectile launched at an angle. the formula would be Viyt+½gt².
ReplyDeleteAlso shutting a bowing arrow is an example of vertical projectile, and can form a parabola depending on the angle arrow is shoot at
ReplyDeletean example of a projectile is when i kick the soccer ball and it goes and falls down like a parabola into the net for a goal (:
ReplyDeleteMy project with andres was a good vertical projectile because it launched in an arched angle by the way i was really impresses with how far it shot.
ReplyDeleteA perjectile is something you going to launch, throw or kick. A good example of a verticly launched projectile is when i throwa football. Its a good example because the ball is travels up then back down cause the force of gravity.
ReplyDeleteAn example of a projectile could be when you are paying volletball and you hit the ball over the net. When you hit it its at a launched at an angle. The hight is from where it was hit to the highest point of the parabola. The range would be from where it was it to where it landed.
ReplyDeleteAn example of a horizontal projectile could be skydiving. A normal range for skydiving would be 10,000 feet. The formula would be delta Y=1/2gt^2.
ReplyDeleteAna Mendoza
correct formula works every time
Deletejumping off a cliff is a comparison to an horizontal angle launch by jumping off the cliff at an angle
ReplyDeleteAn example of a projectile would be my mousetrap cantapult. It shot the marshmallow straight ahead because of how flat it was. More sling shot like. it flew about 3 meters. The marshmallow jumped off my project in a arc-ish way then landed. To know the height you would use the formula Viyt+1/2gt²
ReplyDeleteAn example of a projectile would be someone jumping and travels a certain distance forward. This would be a vertical projectile. It goes in the shape of a parabola and the formula for this would be x=Vx + t. The height and distance depends on the how high the person jumps and travels. The time also depends on the amount of time a person takes to jump that distance.
ReplyDeleteAn example of a projectile would be an airplane lifting off the ground. It would be launched at an angle since it goes up. You can find how high the plane goes by using the formula Vi(y)t + 1/2gt^2 to find delta y.
ReplyDeleteAn example of an angle is a paper football ... You place it down and you flick it and the paper Football goes in the air and reach its height limit Parabola and start going down ... ( I tried of thinking something and this is what I thought :P )
ReplyDeleteThrowing a cannon ball from a cannon would be a projectile. It's launched at an angle.
ReplyDeleteSkydiving would be a projectile because you're launching yourself from a plane.
