Daphney Hilaire 10-5-12 B Period " Newton First law" Applied to a Mouse Trap Car Newton's First Law sates every object persists in its state of rest or uniform motion in a straight line unless it's compelled to change that state by outside forces. There are two parts to this law, one that predicts the behavior of stationary objects and the other that predicts the behavior of moving objects. Newton's law can be applied in my car in the following ways, through the lever, wheels, and string. Newton's First Law is also known as the Law of Inertia. Inertia is the property of a body to resist changes to its state of motion. The application of Newton's Law in the lever, wheels, and string is revealed when the string is fully wound but at rest and the lever is pulled and causes the string to unravel. Motion of change occurs when the string is pulled on. Which then pulls on the wheels and propels the car in motion. This proves Newton's First Law exists because if it weren't for the lever attached to the mousetraps trigger then the wheels would maintain a state of rest. The lever served as an outside force that effected the mouse trap car that was once at rest. If it weren't for the friction between the mousetrap car's wheels and the floor, the mousetrap car would continuously roll. The mousetrap car shows relevance to Newton's First Law because in each the lever, the wheels, and the string was a state of immobility. That state only changed when compromised by an outside force. Also known as a nonzero net force. The inertia of these objects is what kept them from changing. Once changed the state of object will stay changed until acted upon
