Key Stage 3
Meaning
A mechanical energy transfer is when energy from one energy store is transferred to another energy store by the action of a force.
About Mechanical Energy Transfers
- Any time a force causes energy to go from one store into another, it is a mechanical energy transfer.
Examples
 |
 |
 |
| When an object falls energy is transferred by gravity from the Gravitational Potential Energy Store of the object to the Kinetic Energy Store of the object. | The front brakes of this car are glowing from the high temperature. Energy has been transferred by friction from the Kinetic Energy Store of the car to the Thermal Energy Store of the brakes. | When a dragster accelerates energy is being transferred from the Chemical Potential Energy Store of the fuel to the Kinetic Energy Store of the dragster by the force on the piston inside the engine when the fuel reacts with Oxygen. |
Key Stage 4

A mechanical energy transfer is when energy from one energy store is transferred to another energy store by the action of a force.
