Question

2. What do you need to do to calculate the efficiency of any machine

Answer 1

Eff = WO/WI

Step-by-step explanation:

Since work is the change in kinetic energy, the efficiency of a machine can be stated as the percentage of the output work divided by the input work minus the work lost from to friction and heat. Multiply Eff by 100% to get the efficiency percentage.
