Energy
Unit 2.1 Energy
| Term | Definition |
|---|---|
| Absorption | The process of absorbing or of being absorbed |
| Amplitude | A measurement that indicates the height of a wave, from the crest to the trough |
| Diffraction | Spreading of waves around obstacles. |
| Electric Energy | Energy that's stored in charged particles within an electric field. |
| Energy | The ability to do work. |
| Frequency | Number of waves that pass a fixed point per unit time. |
| Intensity | The measurable amount of a property, such as force, brightness, or a magnetic field. |
| Law of Conservation of Energy | A principle stating that energy cannot be created nor destroyed, but can be altered from one form to another. |
| Mechanical Energy | The energy that is possessed by an object due to its motion or due to its position. (can be both KE and PE) |
| Mechanical Wave | A wave that is not capable of transmitting its energy through a vacuum. These waves require a medium in order to transport their energy from one location to another. (Ex. sound wave) |
| Medium | The intervening substance through which impressions are conveyed to the senses or a force acts on objects at a distance. |
| Pitch | The degree of highness or lowness of a tone. |
| Reflection | To throw or bend back (light, for example) from a surface. |
| Refraction | A change in direction of a wave as a result of its traveling at different speeds at different points along the wave front. |
| Transformation of Energy | The process of changing one form of energy to another. |
| Wave | The movement of energy through some medium. |
| Wavelength | The measurement from one wave's crest to another. |
| Potential Energy | The energy of a particle or system of particles derived from position, or condition, rather than motion. (stored energy) |
| Kinetic Energy | The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed. (energy in motion) |
| Transverse wave | A wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves. |
| Longitudinal wave | A wave in which particles of the medium move in a direction parallel to the direction that the wave moves. |
