1.	a worker raises a load of 50 kg from the ground floor to the second floor, which is at a vertical height of 10 meters from the ground. Calculate the gravitational potential energy possessed by the load and also write where did this gravitational potential energy come from?
Answer» END of this section, you will be able to:Explain gravitational POTENTIAL ENERGY in TERMS of work DONE against gravity.Show that the gravitational potential energy of an object of mass m at height h on Earth is given by PEg = mgh.Show how knowledge of the potential energy as a function of position can be used to simplify calculations and explain physical phenomena.
