Week 10 Blog, Due Sunday, November 4th, 2012
We have started talking about Newton's three laws and different types of forces. Observe the world around you and apply the appropriate law to what it is you are observing. Also, include at least one example of force you can observe and name the force(s) involved in the system. Remember, you must complete an original post PLUS comment on another person's post. This must be completed by Sunday, November 4th at 11:00 pm for full credit. If you have any questions, please let me know BEFORE 9:00 pm on Sunday. Happy Posting!

a bird flying is an example of newtons third law because the wings push down and the air pushes the opposite direction keeping it in the air.I think the applied force would be one applied to the bird flying in the air
ReplyDeleteI like that example, I wouldn't of thought of it. I think it might be air resistance as the force?
DeleteNice example, but i would have to agree with edward also as air resistance too.
DeleteVery Creative example!!
DeleteGood example, Kim, and yes the force would be air resistance :)
DeleteAn example of newtons first law is a ball that is at rest until i move the ball with my finger(the unbalanced force) which then makes it start rolling toward whatever direction. The force would be applied caused by my finger.
ReplyDeleteI like your example too. It would have to be an unbalancedforce for it to move because if it was balanced it would stay at rest.Good example
Deletegood example. Your comment is right on
DeleteEverytime i catch a basketball, the object will stay in rest until i throw it to the next person. This is an example of Newtons First law, the unbalanced force of my applied force will cause the ball to move from my hands.
ReplyDeleteWhen a plane flies it is an example of newton's first law (an object in motion stays in motion) and the plane's jets show newton's third law. Every action has an equal and opposite reaction. Forces would include gravity and air resistance
ReplyDeleteGood way to apply both laws in one example and it makes sense too.
DeleteWhen I catch a Softball, the ball stays in rest until I throw it to one of my Team mates. This is an example of Newtons First law, the unbalanced force of my applied force will cause the ball to move from my hands.
ReplyDeleteGood example,I can actually picture the motion of the ball:)
Deletegood example
DeleteWhen the break is suddenly hit on a car, the passengers head will continue to move forward until the seat belt restraints the body from proceeding forward. This is an example of newtons first law of motion.The seat belt's unbalanced force is what restrained movement.
ReplyDeleteThats a really good example 2use
DeleteI like how you mentioned the seat belt, I wouldn't even consider that.. Good example ^^
DeleteNice!! I didn't even think of that...i guess that's why we are made to wear them.
DeleteWhen sitting on a chair your body puts a force on the chair and the chair gives an equal force back.If the chair didn't give the same force you would fall on your butt.That's an example of newton's third law because it states that for every action there is an equal or opposite reaction.And the force applied would most likely be gravitational and normal force.
ReplyDeleteThat would suck if the chair didn't give the same force.
DeleteWhen a car runs out of gas, people usually push it to a safer place. It is an unbalanced force acting on an object. The mass is the car, the person is using force so therefore it is the 2nd law of motion.
ReplyDeleteGood example! Couldn't this also be an example of Newton's First law? You know, the wheels give inertia and the forces have to be unbalanced.
DeleteI agree with guadalupe. Newton's first law could also be used with this example.
DeleteAna Mendoza
When my sister and I fight it would be like Newton's Third law for every action there is an equal reaction. If she hits me, I would hit her back.
ReplyDeletehahaha nice example seleste that's too funny!
Deleteyou are so funny Seleste!
DeleteLol, that's really funny & i would have to say i very much agree:P
DeleteAn example for Newton's First Law of motion could be my dog. Whenever he gets loose and we have to get him, we pull on his leash. He is a stubborn dog though so he usually fights back. He digs his feet to the ground and drags them which can be inertia. We have to pull harder than the force he is using to get him to move.
ReplyDeleteI think that's also third law too I think
DeleteAn example of newton's third law would be when i ran into a glass door which i exerted force and it caused me to fall down.
ReplyDeletehaha thats a good one! Gravitational force would probly be used.
DeleteAn example of Newton's First Law would be a golf ball. The golf ball will remain at rest until it is hit by the golf club (unbalanced force). The forces acting upon the ball would be gravity and normal force when it is on the ground, applied force by the club when it hits the ball, and friction (if the ball stays on the ground). If the ball is hit and it flies into the air, then the force would be air resistance.
ReplyDeleteThis was good example. (: i have never payed gulf -_-
Deletea good example of Newton's 1st law is bowling. The pins stay at rest until the bowling ball's force hits them which causes them to move.one of the forces that are used in bowling is frictional force.
ReplyDeleteGood example I would of never thought of that and applied force could of also been a force used.
DeleteAn example of Newton's third law of motion is when my family and i go to the carnival and get on the Bumper cars. When my car bumps into my mom's car it creates a force and pushes her car. But for every action there is an equal and opposite reaction so my car is pushed back.
ReplyDeletei highly doubt that you have gone to a carnival and played bumper cars with your mom... just saying! just kidding(: good example
DeleteAn example of Newton's first law would be when a car is parked an another car comes and hits it causing it to move. The parked car was not in motion until, an unbalenced force caused it to move. A foce used in this type of situation is applied force because the the car that hit the parked car, applied a certain force on it.
ReplyDeletethese example also applies to the third law as well
DeleteAn example of Newton's third law could be when you push a heavy box. The force you put on the box is equal to its mass times acceleration. The more force you put into pushing the box, the faster it will go. You would be using an applied force in this case.
ReplyDeleteGood example :)
DeleteAnother example of the third law of motion is the keys on a key board, since the keys are push down the push back to the same place having an opposite direction .
ReplyDeleteThat's true, and it actually exerts the same amount of force.
DeleteAn example of the first law of motion would be when you kick a soccer ball. It will remain at rest until acted by an unbalanced force (your foot kicking it). The forces would be normal & gravitational while at rest. Then air resistance while in the air, and friction when its coming to a stop & applied when you kick it.
ReplyDeleteGood example!
DeleteThe newton balls are perfect for the third law is explains the reason for an equal and opposite reaction
ReplyDeleteAn example of the third law of motion is two person on a skate board and they both push each other on the same force .. They both go in different direction causes by the forces the two person did to each other
ReplyDeletethats a good example, i like to think of it as bumper cars going head on
DeleteAn example for Newton's third law of motion is flying a kite. As you're running one direction the wind is blowing against the kite which allows it to fly. The forces applied to this example are air resistance and gravity.
ReplyDeletewell kites are awesome and well it also describes the second law too.
DeletePushing a toy car, it would never stop, but there is friction so it eventually stops, newton's first law.
ReplyDeleteA skydiver jumps out of a plane he starts accelerating downwards, until he reaches max/constant speed. This is the speed at which the drag from air resistance exactly balances the force of gravity pulling him down.The physics of skydiving involves the interaction between gravity and air resistance.Therefore skydiving is awesome and demonstrates Newton's 3 laws of motion by the gravity,parachute,and how fast/the motion.
ReplyDeleteNice unique example! :-)
DeleteAn example of Newton's first law would be when a soccer ball is rolling and a soccer player suddenly kicks the ball (unbalanced force). One force involved would be friction, since the ground is acting upon it.
ReplyDeleteAna Mendoza
Why not include more forces that act is that scenario since there isn't that many anyway.
Deletean example of newtons first law is pushing a car that's in neutral. It's harder to push because the friction caused by the tires and the gravity acted upon the car to the ground
ReplyDeleteBut you ain't about that life to push a car. You need to have a lot of force so hit the weight room. Lol
DeleteAn object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless aced upon unbalanced force. Blood rushes from your head to your feet while quickly stopping when riding on a descending elevator.
ReplyDeleteAn example of Newton's First law would be my cousind playing soccer. The ball will stay at rest until one of them kicks it.
ReplyDeletenewtons first law is object at rest will stay at rest
ReplyDeletesitting on a chair.
ReplyDeleteThe reaction is equal to the force.
If the reaction was bigger than the force, you would be in the air.
If the force was bigger than the reaction, you would be in the ground. 3rd law
that a good comparsion
DeleteI like how you explained it more thoroughly.
Deletewhen I'm playing soccer out side i have to kick the ball which is the first law of motion.
ReplyDeleteA example of newtons first law is a fridge staing in its place unless somebody applies a force to it causing it to move.A force applied would be pushing it.
ReplyDeleteThe example i see is someone skatebording would show newton's first law.When the skateboard is just there it will stay at rest untill someone kicks off.The applied force would be the person pushing it.
ReplyDeleteAn example of Newton's first law of motion would be, when a box is pushed down a conveyor. The forces involved would be the applied force,gravity,and the normal force.
