Newton's 2nd LawThis is a picture of me pushing a fountain across the table. My action as well as the fountains action shows an example of Newton’s second Law. This object is made up of a lot of stuff, therefore its acceleration is going to be low. Because Newton’s 2nd law states that an unbalanced force causes objects to accelerate with an acceleration that is directly proportional to the net force and inversely proportional to the mass. Consequently, as I push the fountain across the table then the fountain has more inertia to resist the change in motion. It is proven that the more mass the more inertia causing the acceleration to be low, the less mass the less inertia causing the acceleration to be greater.

Newton's 3rd Law |
This is a slideshow of Alex hitting a squash ball with a racket in against the wall. This action shows an example of Newton’s third law. When, Alex hits the ball with the racket they both have an equal and opposite reaction. Although the force is equal and opposite of each other, the result is not. As Alex hits the ball the ball will have a greater amount of acceleration than the racket does, because the mass of the ball is less than the mass of the racket. It is stated above, the less mass the greater the acceleration, the more mass the less acceleration it gives off.
