... If the work done by a force doesn’t depend on the path taken by an object, the force is considered to be conservative. An example is the gravitational force. In calculating the work done, the initial and final heights are the only consideration; disregarding the path taken between those two position ...

Friction is a force between two objects in contact
... Friction is a force between two objects in contact. This force opposes an applied force. There are two types of friction, static and kinetic. When an object is pushed, it requires more force to initially set the object in motion. This initial applied force must overcome the objects static friction b ...

... The force exerted by the catcher is opposite in direction to the displacement of the ball, so the work is negative. Or using the definition of work (W = F (Δr)cos ), because = 180º, then W < 0. Note that the work done on the ball is negative, and its speed decreases. Follow-up: What about the wor ...
