Whether the fuel in the car or the gaseous products in its exhaust has higher potential energy is to be determined. Concept introduction: Energy is defined as the capacity to do work. It is associated with both physical and chemical changes. The two types of energy are as follows: 1. Potential energy: It is the energy due to the position of the object relative to the other objects. 2. Kinetic energy: It is the energy that arises due to the motion of the objects.
