1. The problem statement, all variables and given/known data If a force on an object is always directed along a line from the object to a given point, and the magnitude of the force depends only on the distance of the object from the point, the force is said to be a central force. Show that any central force is a conservative force. 2. Relevant equations 3. The attempt at a solution i really dont have a clue.... im guessing work done = force * distance and F = ma might be used but i dont know how!
