Question

In one or two sentences, describe what would happen to the arrows and forces if the surface that the crate was on was ice. (Hint: Ice has almost no friction.)

Answer 1

If the crate were on ice, the arrows representing friction would be significantly reduced, nearly to zero, resulting in less opposing force when attempting to move the crate. This would allow applied forces to easily overcome inertia, causing the crate to accelerate more readily with less effort.
