Newton's 3 laws of motion in pool the game. Nekhi Leonard

Newton's first law of motion- A object in motion will stay in motion except if a force is applied on it, like how an object at rest will stay unless a force is applied on it. The pool ball sits at rest until the pool stick hits the ball to make the ball move.

Ball sitting still until the force hits it.

Newton's second law of motion- The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. The formula for second law is F=m x a The more the object weighs the more force that is applied on it. The pool ball is hit at 100m/s^2 and its mass is 0.70kg what is the force needed to change its direction? 0.70 X 14m/s^2= 70 kg m/s^2 = 70N. Momentum equation is p=mv there is a momentum of 30kg X 2.0m/s = 60kgm/s and there is a momentum of 21kg X v2. V2= 60kgm/s= 21kg X v2 = 2.85m/s.

The balls are in motion after being hit by the white ball.

Newtons third law of motion-For every action there is an equal and opposite reaction. When the white pool ball hits all the others balls at the beginning of the game the balls make a counter reaction but the force applied on the white ball was greater than the force that the other balls had that when the balls scatter all over the pool table.

The force being applied on all the other balls and they try to form a counter reaction to the force applied on them because of the third law.
