Question

In the absence of friction, gravity, and all other external forces, what kind of speed will an object display if it travels from the bottom to the top of an inclined plane?

Answer 1

In the absence of all external forces, any moving object will always travel with constant speed, no matter what kind of surface it moves along; the only thing that can change an object's motion is a force. In the absence of gravity, it doesn't even make much sense to talk about the "top" or "bottom" of an inclined plane
