Masses in contact with each other

  1. Jul 11, 2013 #1
    If 3 masses are in contact with each other I understand that the acceleration is the same for all if a force is applied to the first mass. Is the net force on each object also the same? Assume no friction.

    OK. I imagine you're thinking of something like 3 blocks in a row being pushed along a frictionless surface.

    Is the mass of each object the same?

    No, and hence net force cannot be the same. I see!!! :)
