_______ is the energy required to lift an object of 102 grams, 100 cm straight up, at a constant speed.

Question

A. A Joule

B. Kinetic energy

C. Potential energy

D. Specific heat

E. None of the Above

Answer 1

The energy required to lift an object is the potential energy and is equal to mgh or mass gravity x height. If SI units are used you get joules. But since you dont have 1 kg and 1 meter, the best answer would be (C) potential energy.
