Question

A 1.00 kg box of salt is lifted up 1.25 m above the surface of the Earth to the top of the kitchen counter. The potential energy stored in the salt at this new position is Answer J. Record your answer as a three digit number.

Answer 1

Potential energy is the energy possessed by an object at rest. It is calculated from the product of mass, gravitational acceleration and the height at which the object is rested. We calculate as follows:

PE = mgh
PE = 1.00 kg (9.8 m/s^2) (1.25)
PE = 12.25 J
