Question

Which of the following forms of energy make up the mechanical energy?

Choose all that apply

a) electrical

b) chemical

c) solar

d)kinetic

e) potential

f) magnetic

g) nuclear

Answer 1

Correct Answer: d) kinetic and e) potential

Mechanical energy is related to moving objects. If an object is moving, it is said to have kinetic energy, whereas if it has the ability to start moving (if left to itself) it has potential energy. An example of this is a ball left from certain height moves because of potential energy. Another example of potential energy is a mass at the end of a compressed spring, which will fly away if the spring is allowed to decompress.
