||||
| Potential Energy | Stored energy; the energy an object has due to its position, molecular arrangement, or chemical.
🗑
|
||||
| Heat | The flow of energy from one object at a higher temperature to an object at a lower temperature.
🗑
|
||||
| Conduction | Process by which energy is transferred by physical contact (collision of molecules).
🗑

||||
| Wave | A disturbance that moves energy from one place to another.
🗑
|
||||
| Longitudinal wave | A wave, in which, displacement of the medium is parallel to the direction of the energy.
🗑

||||
| Transverse wave | A wave, in which, displacement of the medium is perpendicular to the direction of the energy.
🗑
|
||||
| Amplitude | The maximum amount of displacement in a medium caused by the wave.
🗑
