Friction on top of object with frictionless surface???? 1. The problem statement, all variables and given/known data If an object1 has friction between it and object2, and object 1 rests on object 2, when a force is appliced to object 1 that is horizontal, what impact will it have on object 2 when the surface object 2 is on has negligible friction. 3. The attempt at a solution This isn't the exact problem, but this is the part that i cannot understand. According to the answers in the back of the book, object 2 seems to be experiencing a force that is equal to that of object 1, minus the static friction. Whereas object 1 uses the kinetic friction to get its net force. I dont understand why this would be, if it even is.
