Answer the following :

Give one example to illustrate that heat can be generated from the energy of motion.

During any motion all the energy provided is not converted to useful work some of the energy is released in other forms. Relative motion between two objects will produce heat due to the release of energy which causes the molecules of the substance to move faster. While driving a car, the road and tires will be in contact and have motion between them due to which tires will be heated. This is because of the friction between tires and road which will cause tires to heat up.
