Two Types and Nine Forms of Energy
Practice 11 energy terms with the same definitions in every activity.
Focused extension practice. Gravitational, elastic, and chemical use their full potential-energy names. Mechanical energy includes motion and position. Forms can involve both kinetic and potential energy; they do not all fit into just one type.

Study guide — 11 terms
| Term | Meaning | Example |
|---|---|---|
| potential energy | Energy associated with the positions or arrangements of interacting objects or particles. | A raised gate has potential energy because of its position. |
| kinetic energy | The energy of motion. Faster or heavier objects have more. | A bicycle gains kinetic energy as it speeds up. |
| gravitational potential energy | Energy associated with the relative positions of masses; near Earth, raising an object above a chosen reference level increases it. | A lifted backpack has gravitational potential energy. |
| elastic potential energy | Energy associated with stretching or compressing an object, such as a spring. | A bent diving board stores elastic potential energy. |
| chemical potential energy | Energy associated with the arrangement of atoms and electrons, which can change during a chemical reaction. | A snack provides chemical potential energy for your body. |
| nuclear energy | Energy associated with atomic nuclei, released or absorbed when nuclei change. | The Sun releases nuclear energy when light nuclei combine. |
| mechanical energy | The energy an object has from its motion and position. | A swinging playground swing has mechanical energy from its motion and position. |
| thermal energy | Energy associated with the random motion and interactions of particles in matter; it depends on the amount, type, and state of the material as well as its temperature. | A large pot of warm water has more thermal energy than a small cup at the same temperature. |
| sound energy | Energy carried by vibrations moving through matter. | A vibrating guitar string sends sound energy through the air. |
| radiant energy | Energy carried by light and other electromagnetic waves. | Sunlight carries radiant energy through space. |
| electrical energy | Energy carried by moving electric charges. | A working electric fan receives electrical energy through its cord. |
