NEWTON's laws of motion

[doc.madani]

hello can some one help me, post a simplified version of Newton's 3 laws of motion and some examples thank you very much :)

Hey Doc.Madani

1. A physical body will remain at rest, or continue to move at a constant velocity, unless an outside net force acts upon it.

Imagine a ball moving through space at a constant velocity, until a force act on that ball it will continue to move with that constant velocity.

2. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma.

I am sure you have used examples using F = ma. Say a ball of mass 2 Kg is moving with an acceleration of 5 ms. The force exerted on the ball is 10 N.

3. To every action there is an equal and opposite reaction.

If you exert a force on a wall of 10 N and the wall doesn't move, it is exerting a force of 10 N back.


Somebody might want to touch up on these, if there are any small problems. Those are not the actual laws, but watered down versions.
