Energy Practice Worksheet
| # | Answer |
|---|---|
| 1 | Energy is the ability to do work or cause change. |
| 2 | Examples include heat, light, electrical, chemical, or kinetic energy. |
| 3 | Kinetic energy. |
| 4 | Chemical energy. |
| 5 | Thermal energy or heat energy. |
| 6 | No, energy is not matter, so it is not a solid, liquid, or gas. |
| 7 | Some of the energy changes into other forms, such as heat and sound. |
| 8 | Energy cannot be created or destroyed, only changed from one form to another. |
| 9 | Elastic potential energy. |
| 10 | Gravitational potential energy. |
| 11 | Chemical energy changes into electrical energy and then light energy. |
| 12 | Energy can be transferred by heating, light, sound, electricity, or movement. |
| 13 | Walking upstairs uses more energy. |
| 14 | Friction and air resistance transfer some of the bicycle's energy to heat and sound. |
| 15 | Chemical energy. |
| 16 | Electrical energy. |
| 17 | Light energy and thermal energy. |
| 18 | Because heat can transfer energy and cause changes such as warming objects or changing states. |
| 19 | Examples include a toaster changing electrical energy to heat energy or a plant changing light energy to chemical energy. |
| 20 | Energy is important because chemical reactions need energy to start or release energy when reactions happen. |
