Newton's Laws of Motion

Sir Isaac Newton is an established philosopher and mathematician. He was known as one of the greatest minds of the 17th century Scientific Revolution. He discovered in optics, motion and mathematics which made him produce the principles of modern physics. He made 3 laws which are called the Newton's Laws. The first Law is called the Law of Inertia. The second law is called Law of Acceleration and the last law is called the Law of Action/Reaction. The Law of Inertia is when an object remains at rest or stationed, until a force is applied to it. Remember it can be anything such as a leaf, a bottle, a human being, and even the wind. The Law of Acceleration in based on an equation. The equation is F(Force)=M(Mass) x A(Acceleration). This basically means the greater the mass of an object, more force will be needed for it to accelerate. The Law of Action/Reaction is for every action, there is an equal and opposite reaction. For example, when jumping on a trampoline, the action is pushing down onto the tramp and the reaction is the tramp pushing you back up. The game we played demonstrated Newton's Laws because there were balls bigger and smaller than others. Before we hit the ball, it would be at rest, this relates to Newton's first law. The amount of force we applied for the ball to hit the bigger ball, depended on the size of the ball we threw. This relates to Newton's second Law. When we hit the ball with a smaller ball, the action will be us throwing and hitting it and the reaction will be the big ball going forward as we applied force. This relates to Newton's third law.
Here is a short video of what we did.
