Energy
words and concepts associated with energy
| Question | Answer |
|---|---|
| energy | The ability to change matter |
| potential energy | Energy that is due to the position or condition of an object |
| Kinetic Energy | Active energy (Energy in Motion) |
| mechanical energy | energy that moves matter |
| thermal energy | the movement of molecules |
| chemical energy | Potential energy caused by the arrangement of molecules in matter |
| sound energy | Energy caused by the vibration of matter |
| light energy | Comes from photons (allows us to see) |
| nuclear energy | Comes from the fusing or fission of the nucleus of atoms. |
| electrical energy | Comes from the movement of electrons through atoms. |
| solar energy | energy from the sun |
| Conservation of Energy | Energy is neither created or destroyed. It only changes forms. |
| What unit is energy measured in? | Joules |
| Work | The force exerted on an object multiplied by the distance |
| What is the formula for work | Work = Force x distance |
| What is the Formula for force | Force = mass x acceleration |
| Energy | the ability to do work |
| Gravitational energy | potential energy due to an objects position above the Earth's surface |
| Elastic Energy | potential energy due to an objects shape |
| Chemical Energy | potential energy stored in chemical bonds |
| volume | The amount of space an object takes up |
| velocity | and objects speed and direction |
| acceleration | a change in speed |
| Formula for kinetic energy | (KE) = 1/2mass x Velocity^2 |
| Formula for potential energy | (PE) = mass x gravity x height |
