Is the work done walking up an escalator in the same speed and opposite direction of the escalator zero?

Why does a conservative force return the work done against it by a body to that body?

A force is exerted on a body, kinetic energy increases but no work is done by the force. Why?

Is it possible to have a non-conservative vector field, such that the closed loop integral is $0$ for only some specific path(s)?

Why work $W$ and heat $Q$ are different concepts?

What is the relationship between force and kinetic energy?

Does the displacement in the definition of work correspond to the displacement of the object or the point of application of the force?

What exactly is “electrical energy”?

Is any work done if I walk in a circle?
