Key Stage 4
Meaning
Energy stores can be calculated from other known facts about an object.
About Calculating Energy Stores
- Calculating energy stores can be done using information about properties, distances, motion and fields affecting an object.
The following energy stores can be calculated from other quantities:
- Thermal Energy = Mass x (Specific Heat Capacity) x (Change in Temperature)
- Elastic Potential Energy = 0.5 x (Spring Constant) x (Extension)2
- Kinetic Energy = 0.5 x (Mass) x (Speed)2
- Gravitational Potential Energy = (Mass) x (gravitational field strength) x (change in height)
