Newton's third law?

Question

What are some examples of Newton's third law?

Answer 1

How about a Rocket in space..... the little particles of the fuel fly out through the back which makes the rocket to actually move ... there is not air in space obviously so the rocket itself has nothing to push against... the fuel pushes against the rocket making it move forward

Answer 2

When you walk, you go forward. That's Newton's third law at work. Notice that when you walk, what you are actually doing is pushing the ground backward with your feet. Newton's 3rd law says that whenever a body A (you) exerts a force upon a body B (the Earth), then body B will exert a force of equal intensity but opposite direction on body A (you). It turns out therefore that the Earth impels you forward with the same intensity as you try to push it backwards.

Now, you might wonder what happens to the Earth when you push it backwards. Well, the intensity of the force with which you push it back is the same as the intensity of the force with which it pushes you forward, but since the Earth has a lot more mass, that doesn't seem to bother it too much, while the same force goes a long way toward moving you to your destination.

Answer 3

Newton's third law stated that for every action, there will be a reaction with same magnitude but in opposite direction.

For example, you try to pull heavy door and opened it and at the same time, you feel the door is pulling you too. But another question might arise from this example, if the door is "pulling" you with the same magnitude of force, then why the door opened?

another example is when we stand on the ground, we are actually putting force on the ground, F = mg (weight of our body). But why do we doesn't penetrate "into" the ground? It because there are a reaction force with the same magnitude of our weight but directed upward. It balance and cancel each other out. As the result, we can stand on the ground.

Answer 4

Newton's 3rd law = For every action, there is an equal and opposite reaction

Example: When you throw a ball toward a wall and it comes back
Example: A means of propulsion by expelling air (action) and the thrust created proppells the object in the opposite direction (reaction)

Answer 5

If you hit a person in the face their face hits you back with equal force which is why you can break your hand.

When your foot pushed back on the ground the ground pushes you forward which is why you can go forward. If the ground did not push back you couldn't move. Sometimes ice can get nearly this frictionless.

If a bird and a mac truck have a head on collision, the bird applies exactly as much force to the truck as the truck applies to the bird. However, the difference in mass means the bird will have a far greater acceleration because it has a far smaller mass. Splat.

Sorry about the image. Physics can be messy though.

Answer 6

Newton Third Law:
Every action has a reaction equal in magnitude & opposite in direction.

Think of every " action " u do, & u will know whats its " reaction "

Answer 7

For every action there is an equal and opposite reaction. Imagine pushing a door open. The force is only visible in one direction. Now imagine pushing the door open while wearing roller skates. The equal and opposite reaction will cause you to roll backwards.

Answer 8

Newton's theory of motion included the movement of the planets, the falling of things like apples, the trajectory of cannon balls, and the swing of a clock's pendulum .... that's the theory ...never heard of third law (one & the same)?

Answer 9

playing pool, you are aiming for a ball that is stationary, you hit the white cue ball with the cue stick. the momentum of the cue ball when it hits the ball you are aiming for passes its momentum into the other ball. this causes the white ball to stop or slow down, and the other ball to gain the speed and momentum that the white ball had.

otherise the equal and opposite reaction would be like a see saw one side is forced down and the other side is pushed up

Answer 10

some examples of newton's 3rd law (action = reaction)are bouncing ball, spring and jumping
