| Frage | Antworten |
| How to find time with distance and velocity? | Distances divide by velocity. |
| What is the conservation of energy law? | Energy can neither be created or destroyed but it can be changed from one form to another (or passed between objects) |
| Why is energy important? | It is required to make things happen. |
| What is a Joule? | A unit of energy. |
| What is potential energy? | Energy stored in a object due to its position. |
| What is heat energy? | Energy that is possessed by all hot objects. |
| What is chemical potential energy? | Energy held in bonds between atoms. |
| What is kinetic energy? | Energy possessed by all moving objects. |
| What is a Watt? | A unit of power. |
| What is electrical energy? | Energy carried by moving charges |
| Gravitational potential energy? | Energy possessed by all objects which are high up |
| What is elastic potential energy? | Energy stored in squashed or stretched objects |
| What is nuclear potential energy? | Energy stored in the nucleus of an object. |
| When would an object have more kinetic energy? | When it increases speed |
