THE GREAT RACE

The car I have built is an example of all three of Newton’s laws of motion. Newton’s first law states that every object continues in its state of rest or in uniform motion in a straight line unless it is compelled to change that state by forces acting on it. As seen in my car, it was at rest until the thread was wound back which caused the car to move forward. Newton’s second law of motion states that the acceleration of an object is directly proportional to the net force acting on the object (in the direction of the net force) and inversely proportional to the mass of the object. In the process of making my car I had to consider both the mass of my car and the right amount of energy to create a great enough force allowing the car to achieve maximum acceleration. Newton’s third law states that for every action there is an equal and opposite reaction. The string which is tied to the trap is wound tightly and the trap is held. When the trap is released, the string unwinds propelling the wheels forward as they push on the floor and the floor pushes back. Thus I have built a mouse trap car which exemplifies all three of Newton’s laws of motion.
