The energy an object has from its atomic structure The energy an object has from its chemical composition The energy an object has from it position or condition The energy an object has from its motion When does an object have no kinetic energy? When it's at rest When it is slowly moving When it has no electrical charge When gravity is the only force that is acting on it Which object has the most potential energy? A ball resting on the edge of a cliff A ball on top of a refrigerator A ball being thrown at 90 miles per hour A ball laying on the ground When is potential energy transformed into kinetic energy? When an object at rest is lifted to a higher elevation When an object at rest remains at rest When an object in motion is stopped and put at rest. When an object at rest is put into motion What is the best synonym for potential energy? Mechanical energy Electrical energy Energy of motion Stored energy Kinetic and potential energy are the two types of energy that relate to: Density Change Motion Friction Which of the following has the most kinetic energy?
