Friction between solids can be most accurately defined as the force that enhances the sliding motion of two surfaces that are touching each other.

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
