brief statements of the three laws:
1st law :A physical body will remain at rest, or continue to move at a constant velocity, unless an outside net force acts upon it.
2nd law; Rate of change of momentum is proportional to the resultant force producing it and takes place in the direction of that force.
3rd law :To every action there is an equal and opposite reaction.
Examples of the three laws of motion are :
The ball is staying at rest without an outside force pushing it. This is an example of the first law of motion.
The ball moves to the right because the outside force hit the ball to the right. This is an example of the second law of motion.
When the balls hit they bounced in the opposite direction. This is an example of the third law of motion.
