Energy Transformation on a Roller Coaster
A roller coaster ride is a thrilling experience that includes a wealth of physics. Part of the physics of a roller coaster is the physics of work and energy. The ride frequent begins as a chain and motor (or another mechanical device) exerts a force on the train of cars to lift the train to the top of a very tall hill. Once the cars are lifted to the top of the hill and gravity takes over and the remainder of the ride is an experience within energy transformation.
Inertia: the resistance an object has to a alter in its state of motion. Newton's first law of motion declares that force is NOT required to keep an object in motion. Slide
