What is law of motion?

There are three of them. Try googling for Newton’s Laws and you’ll find them very quickly.

@Neha153 Are you just trying to get us to do your homework?

When I say ooh… you say ahhh.

Remember what happens when you try to step into a canoe that is moored to a dock? That’s evidence of one law. Falling out of the canoe is proof of another one.

Newton’s laws:
1. An object in motion remains in motion and an object that is not in motion remains at rest.
2. F net = ma (sum of forces = mass x acceleration)
3. For each action, an equal and opposite reaction is exerted, e.g. you push down on Earth, Earth pushes you up.
