Newton’s First Law 

While Kevin is running through the hallway he bumped into Jamie, and that causes the pencil on Kevin’s textbook to keep moving forward the speed that Kevin was originally travelling at. The Law of inertia may not always seem to apply. If the angle of the textbook was a different way or there was a fold in it, the pens velocity may had been different.

Newton’s Second Law

In this example of Newton’s second law we show a mass with a constant mass needs an unbalanced Force (in this case the hand which I the applied force) to accelerate. Sometimes the force of friction may not always be constant (a bump in the table, or water) this may be why it sometimes appears that Newtons Second Las doesn’t necessarily apply.

Newtons Third Law 

Newtons Third Law explains that every action has an equal or opposite reaction. so in this case the ball is dropped. The force on the ball exerted on the floor is equal in magnitude to the force the floor exerts on the ball. If the shape of the ball is distorted in some way it may affect the direction the ball bounces back up.
