Webg = 9.8 m/s 2. Potential energy = m × g × h = 588 J. Question 8. An object of mass 12 kg is at a certain height above the ground. If the potential energy of the object is 480 J, find the height at which the object is with respect to the ground. (g = 10 m/s 2) Solution: m = 12 kg. Ep= 480 J. Ep = m×g×h. WebAns: Work is said to be done when a force acts on a body and moves it in the direction of the force. Greater is the force acting on a body and longer is the distance moved by it, larger would be the work done. Mathematically, Work is a product of force F and displacement S in the direction of the force. Thus. Work done = Force x displacement.
