Student Exploration: Energy of a Pendulum Wocabula~: conservation of energy, gravitational potential energy, kinetic energy, pendulum, potential energy, velocity Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. A toy car is about to roll down a track, as shown below. At what point do you think the car will reach its greatest speed? 2. A pjijdjil(iri consists of a weight that is suspended from a pivot. At what point will the pendulum below move fastest? Mark this point on the image. Mark this point on the image. 3. What do these two situations have in common?
