Static friction is the moving force of the top block. Potential energy is being stored in the spring, which is attached to the bottom block. Can we tell that static friction is connected with a potential energy?
Homework Statement
Suppose we have a two blocks of masses m1 and m2, one on the top of another. The lower block is attached to a spring which is attached to the wall. These two blocks are on a zero-friction floor. We give the lower block a velocity so that the upper block is not sliding on the...
