Vocabulary: friction- the resistance that one surface or object encounters when moving over another . gravitational potential - the scalar quantity characteristic of a point in a gravitational field whose gradient equals the intensity of the field and equal to the work required to move a body of unit mass from given point to a point infinitely remote. energy - the strength and vitality required for sustained physical or mental activity. kinetic energy - energy which a body possesses by virtue of being in motion.Compare with potential energy .
Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Sally gets onto the roller coaster car, a bit nervous already. Her heart beats faster as the car slowly goes up the first long, steep hill. 1. What happens at the beginning of every roller coaster ride?
