That's why I only paid attention to the forces acting in the x-direction. May be positive or negative depending on the. May be positive or negative depending on the choice of coordinate system. Fgrav and Fnorm do not do work since a vertical force cannot cause a horizontal displacement.

However, if the object is raised at a steady speed, it is in equilibrium and the lifting force will just balance weight. If there were friction, what would the force of. This of course ignores any air resistance etc. Work is done on the car usually by a chain to achieve this initial height.
False According to what I have studied when balanced forces are on an object, that. Then calculate the work done by these forces. This is due to balanced forces acting on the ball.
