Answer:
Friction is responsible for many types of motion. It helps us walk on the ground. Brakes in a car make use of friction to stop the car. Asteroids are burnt in the atmosphere before reaching Earth due to friction. Friction enables us to walk freely. It becomes possible to transfer one form of energy to another. Objects can be piled up without slipping. Breaks of vehicles work due to friction. It always resists the motion, so extra energy is required to overcome it.
