Efficiency
All machines waste some energy when they transfer
- Most machines waste energy as heat energy
- The efficiency of a machine is a way of saying how good it is at transferring energy into useful forms
- A very efficient machine has an efficiency that is nearly 100%. The higher the efficiency, the better the machine is at transferring energy into different forms.
