Which energy is stored in an object when it is raised above the earth's surface?

Think it through first, then pick an option.

  1. a kinetic energy
  2. b potential energy
  3. c heat energy
  4. d chemical energy
Answer and explanation

Correct answer: b potential energy

When an object is raised, the work done in lifting it is stored in it as potential energy mgh.

Why the other options are wrong

  • a kinetic energy: This is not the answer: When an object is raised, the work done in lifting it is stored in it as potential energy mgh.
  • c heat energy: This is not the answer: When an object is raised, the work done in lifting it is stored in it as potential energy mgh.
  • d chemical energy: This is not the answer: When an object is raised, the work done in lifting it is stored in it as potential energy mgh.
