Newton's Laws of Motion
By: Sylvia Phillips
Newton's first law of motion states that an object in motion will stay in motion and an object at rest will remain at rest unless acted on by an unbalanced force. In this picture the box (the object) is being pushed by the person (the unbalanced force), causing it to accelerate.
Newton's second law states that the force of an object is equal to its mass times its acceleration. In the visual the truck's mass is affecting its acceleration, thus taking it a longer time to come to a stop.
Newton's third law states that for every action there is an equal an opposite reaction. In the visual, one ball is being lifted and then let go. The kinetic energy travels through the three additional balls and then creates an opposite reaction by propelling the fifth ball up to the equal height of the first ball.
