When a person walks on surface the frictional force exerted by the surface on the person is opposite to the direction of motion true or false

Text Solution

Verified by Experts

False. In frictional force exerted by the surface on the person is in the direction of his motion. Frictional force acts as an external force to move the person. When the person trying to move, he gives a push to ground on the backward direction and by Newton.s third law he is pushed by the ground in the forward direction. Hence frictional force acts along the direction of motion.
