1
Q
Efficiency
A
An object’s efficiency is a percentage showing how much work has been done, compared to how much energy was given to the system.
2
Q
Efficiency Equation
A
Efficiency (%) = energy output/energy input * 100
Energy output is how much energy has been used for useful work (J). Energy input is how much energy has been given to the system (J). Higher efficiency means higher values, vice versa.
