I'm learning about Work for the first time. Work = (force) x (distance moved in the direction of the force) I understand what work is when it comes to lifting objects. but if you had an object moving at constant velocity with no opposing forces, and apply some force to it in the...

Thank you all. It's hard to accept that an object moving at constant velocity is essentially moving by itself!

If it was equal to gravity the object will lie still, right? :confused:

That doesn't make sense. A car can move at constant velocity by generating constant forces to counteract the resistive forces it faces. If I push a book on a table to make it move at constant velocity, the net force will not be zero initially but once the book gets moving my force will equal...

Hello If an object of certain mass is being pulled upwards at constant velocity (and with a constant force) then by Newton's first law of motion, the net force acting on the object is zero. So the force pulling the object upwards must be equal to the force pulling/pushing it down. The...
