write story on friction in 300 words
Answers
Friction is a force that acts to stop the movement of two touching things. The energy lost to friction is turned into sound and heat. Two kinds of friction are static and kinetic. Static friction is when the friction is strong enough to stop movement between two objects. Kinetic friction is used when the frictional force is not strong enough to stop all motion. An effect of kinetic friction is heat production.

These bumps are called asperities. As these two rough surfaces move against each other they get stuck and prevent motion until the asperities are broken or slid over. Even the smoothest materials have these asperities
