Work done is the measure of the energy transfer that occurs when a force is applied over a certain distance. It is calculated by multiplying the magnitude of the force by the distance moved in the direction of the force.
Friction is a force that opposes motion and reduces the amount of work done. The greater the friction, the more work is required to overcome it. Therefore, work done is directly proportional to the force of friction.
The coefficient of friction is a measure of the amount of friction between two surfaces. The higher the coefficient of friction, the more work is required to overcome the friction between the two surfaces.
Yes, work done can be negative in a friction problem. This occurs when the applied force is in the opposite direction of the motion, meaning that the object is losing energy and work is being done against the force of friction.
Examples of work done and friction can be seen in everyday activities such as pushing a heavy object, walking on a rough surface, or riding a bike. In each of these cases, work is done to overcome the force of friction between surfaces.
