Q: The potential energy of an object increases with its-
  • A. Velocity
  • B. Height
  • C. Displacement
  • D. Distance
Correct Answer: Option B - Potential energy of an object increases when it raised through a height. This is because work is done on it against gravity while it is being raised. The energy present in such an object is the gravitational-potential energy. This gravitational-potential energy of an object at a point above the ground is defined as the work done in raising it from the ground to that point against gravity. An object of mass when raised through a height from the ground, then work done on the object will be W = force x displacement = mg x h = mgh
