1. What is potential energy? The energy an object has from its atomic structure The energy an object has from its chemical composition The energy an object has from its motion The energy an object has from it position or condition 2. What is kinetic energy? 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 3. 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 4. 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 5. When does a yo-yo have the most potential energy? When it's going between the highest and lowest points. When it is moving at top speed When it is at it's lowest point When it is at it's highest point 6. 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 7. What do potential and kinetic energy have in common? They are both related to density They are both unrelated to mass. They are both related to volume They are both related to motion 8. Four cars are positioned at the top of a hill. Which car has the most potential energy? A C B D 9. What is the best synonym for potential energy? Mechanical energy Electrical energy Energy of motion Stored energy 10. Why do objects at high elevations have more potential energy than objects at low elevations? Because the thinner air at higher elevations means objects have a greater potential to move very fast. Because objects at high elevations are closer to the sun, which is the source of all energy on earth. Because objects at high elevations tend to move slower than objects at low elevations. Because gravity gives objects at high elevations the potential to fall much further. 11. Kinetic and potential energy are the two types of energy that relate to: Density Change Motion Friction 12. Which of these has the most potential energy? A C B D 13. What is potential energy? The stored energy of an object due to its position or condition The energy that an object has due to it motion. The energy an object has due to its speed The energy an object has due to its volume 14. What is kinetic energy? The energy an object has due to its mass The energy an object has due to its existence. The energy that an object has due to its motion The stored energy of an object due to its position or condition. 15. Which passenger has the most potential energy? A B C D 16. The amount of kinetic energy an object has depends on its: Mass and speed Speed and density Volume and friction Volume and mass 17. Which of the following has the most kinetic energy? A tractor-trailer traveling at 80kph A car traveling at 80 kph A cheetah running at 80 kph A motorcycle traveling at 80 kph 18. When is kinetic energy transferred from one object to another? When those objects pass one another When the first object is bigger than the second. When the first object has more potential energy than the second object When the two objects collide 19. In a generator, kinetic energy is transformed into: Potential energy Electricity Motion Solar power 20. There is a finite amount of energy in the universe. What does this mean? Energy is created and destroyed all the time There is a limited amount of energy in the universe Stars generate most of the energy in the universe. Dark matter absorbs most of the energy in the universe. |
