LAWS OF MOTION

1st law of motion

A object in motion tends to stay in motion, and an object at rest tends to stay at rest, unless an outside force acts apon the object. For example, when you throw a ball it will fall, because of gravity. If you were in space and you threw the ball it would never stop because there is no gravity.

Newtons 2nd law

The acceleration of an object as produced by a net force is directly proportional to the magnitude to the net force in the inversely proportional to the mass of the object.

Newtons 3rd law

For every action there is an equal and opposite reaction. For example if you push something heavy in space it will push you backwards.
