Question

Identify the energy which can be used directly in its form?

• A. potential energy
• B. kinetic energy
• C. solar energy
• D. heat
• E. renewable energy

Answer 1

The correct option is A potential energy

Potential energy stored cannot be directly used to do some work. Kinetic energy and heat energy can be used to do some mechanical work, however the potential energy first needs to be converted to one of the other forms and then mechanical work can be done from that energy.
