Other Forms of Energ
Topic 3, Lesson 3: Other Forms of Energy
| Term | Definition |
|---|---|
| Mechanical Energy | Is the energy an object has due to its motion, shape, position, or a combination of these factors. It equals the total potential and kinetic energy of an object. |
| Mechanical Energy Formula | = potential energy + kinetic energy |
| Nuclear Energy | Is a type of potential energy stored in the nucleus and is released through a nuclear reaction. There are two types, fusion and fission. |
| Fusion | A type of nuclear energy where small nuclei combine to form larger nuclei. This kind of nuclear energy releases more energy. |
| Fission | A type of nuclear energy when a nucleus splits into smaller fragments. When it breaks apart it releases energy. |
| Thermal Energy | The total potential and kinetic energy of the particles in an object or substance (solid, liquid, or a gas). |
| Heat | The transfer of energy into the thermal energy of an object (an increase in temperature). |
| Thermal Energy and Particle Movement | The particles move more quickly and spread further out as they have an increase in thermal energy (an increase in temperature). Is from this movement that heat and temperature are created. |
| Relationship between thermal energy, kinetic energy, particle movement, and temperature | When a substance is at a high temperature, its particles are moving quickly and have more kinetic energy. If the kinetic energy of the particles in a substance increases, the thermal energy of the substance also increases. |
| Chemical Energy | Is a form of potential energy because it results from the relative position of the particles within a material held together by chemical bonds. When these bonds break, energy is released. |
| Electrical Energy | Is the energy of electric charges. Different materials and particles have different charges, which can result in the movement of electrical charge (electricity). If not moving, then it has electrical potential energy. |
| Electromagnetic Radiation | Is a form of kinetic energy that travels through space in waves. It does not need a medium to travel. |
| Medium | Matter through which a wave can travel, such as water, air, or metal |
| Solid non-moving objects | Have kinetic and potential energy. The particles of the solid object are in constant motion, so they have kinetic energy. The particles also have potential energy due to their arrangement in the object. They also have other forms of potential energy. |
