To determine whether the statement "When a person walks on a rough surface, the frictional force exerted by the surface on the person is opposite to the direction of his motion" is true or false, we can analyze the situation step by step. ### Step-by-Step Solution: 1. **Understanding Friction**: Friction is a force that opposes the relative motion between two surfaces in contact. It acts in the direction opposite to the movement of the object. 2. **Identifying the Motion**: ...
