Dear student,

Efficiency is a quantitative measurement of the ability of the machine to convert input energy into output energy.
Now input energy can be in the form of chemical energy as in case of a car as a machine, hear input energy is provided by the petrol.
So the output energy will be the mechanical energy with which the car is moving that is kinetic energy.
If the car can convert all the chemical energy that is fuel into the mechanical energy, it is said to be 100% efficient.
But there is no machine in the universe that is 100% efficient.
The question can be asked to calculate the % efficiency of a machine.

Hope this helps,
