Kinetic & Potential
Topic 3, Lesson 2: Kinetic Energy and Potential Energy
| Term | Definition |
|---|---|
| Kinetic Energy | is the energy that an object possesses by virtue of being in motion, the energy of motion |
| Factors that affect kinetic energy are | speed and mass |
| Kinetic Energy Formula | 1/2 x mass x (speed squared) |
| Kinetic energy is measured in | joules (J) |
| Factor that has the largest affect on Kinetic Energy is | speed because it is squared in the equation |
| Potential Energy | energy that results from the position or shape of an object. This form of energy has the potential to transform into kinetic energy/do work |
| Gravitational Potential Energy | This type of potential energy is related to an object's vertical position - how high it is above the ground |
| Gravitational Potential Energy Formula | weight x height above the ground |
| Gravitational Potential Energy is measured in | joules (J), like kinetic energy |
| Gravitational Potential Energy is affected by the object's | weight and height above the ground |
| Elastic Potential Energy | this type of potential energy is associated with objects that can be compressed or stretched, it's shape |
