Energy Transfer
Energy Transfer & Transformation
| Term | Definition |
|---|---|
| Energy Transfer | Energy moving from one object or place to another. Example: When you touch a cold doorknob, heat moves from your hand to the metal. |
| Energy Transformation | Energy changing from one form to another. Example: A flashlight changes chemical energy in the battery into light energy. |
| Thermal Energy | Energy related to heat and the movement of particles in a substance. The faster the particles move, the more thermal energy it has. |
| Electrical Energy | Chemical energy is the energy stored inside the bonds of molecules. It is released when a chemical reaction happens, like when food is broken down in your body or when fuel burns. |
| Electrical Energy | Energy from the flow of electric charges (electricity). It powers things like lights, computers, and TVs. |
| Nuclear Energy | Energy stored inside the nucleus of atoms. It is released in nuclear power plants or in the sun. |
| Mechanical Energy | The energy an object has because of its motion or position. A moving car or a stretched bow has mechanical energy. |
| Sound Energy | Energy carried by vibrations that travel through air or another medium. We hear sound when these vibrations reach our ears. |
| Gravitational Energy | Energy an object has because of its height above the ground. The higher an object is, the more gravitational energy it has. |
| Radiant Energy | Energy that travels as waves through space, such as light from the sun. |
| Elastic Energy | Energy stored when something is stretched or compressed. Examples: rubber bands, springs, trampolines. |
| Electromagnetic Energy | Energy that travels in waves and can move through empty space. It includes light, radio waves, microwaves, and X-rays. |
| Motion Energy (Kinetic Energy) | The energy of a moving object. Anything in motion—like a rolling ball—has kinetic energy. |
| Hydropower Energy | Energy made by moving water. Flowing or falling water turns turbines to make electricity. |
| Potential Energy | Potential energy is stored energy. It is the energy an object has because of its position or condition. Example: A book on a high shelf has potential energy because it could fall. |
| Kinetic Energy | Kinetic energy is the energy of motion. Any object that is moving has kinetic energy. Example: A rolling ball has kinetic energy because it is moving. |
| Conductor | A substance that readily transfers heat or electrical energy. |
| Insulator | material that does not conduct heat or electrical current. |
| System | A group of interacting or interdependent elements forming a complex whole; forexample, all the factors or variables in an environment or all the variables that mightaffect a science experiment. |
| Energy | The ability to do work |
