SUMMARY
The discussion clarifies the distinction between muscular force and normal force. Muscular force is the force exerted by muscles on a body, while normal force is the contact force that acts perpendicular to the surface of contact between two bodies. When a person pushes or pulls an object, the force applied is classified as muscular force, whereas the normal force arises from the interaction between the hand and the surface of the object. The relationship between these forces can be mathematically expressed as the resultant contact force, which is calculated using the formula √(N² + f²).
