Answer 2

Work Done to Overcome Friction

The work done to overcome friction depends on various factors such as the nature of the surfaces in contact, the normal force, and the coefficient of friction. Here are some key points based on the search results:

- The work done to overcome friction is influenced by the coefficient of friction, the normal force, and the distance over which the force is applied. - The percentage of work done to overcome friction varies: 25-35% for sliding friction, 15-25% for rolling friction, and 40% for fluid friction. - The work done to overcome friction can be calculated using the formula W = Fd, where W is the work done, F is the force applied, and d is the distance over which the force is applied. - In the case of rolling friction, the work done is influenced by the radius of the rolling object and the force applied.

In summary, the work done to overcome friction is influenced by factors such as the nature of the surfaces in contact, the normal force, and the coefficient of friction. The percentage of work done varies for different types of friction, and the calculation of work done involves the force applied and the distance over which the force is applied.
