Web10 de abr. de 2015 · The static friction is a force that acts on A so W T = T x a = 0. But when the object slides then the friction force is constant and equal to T = μ N and is is always opposite to the velocity of the body. So then W T = − T s where s is the total space traveled by the body. Share.
