What term is used to refer to the ability to do work?

  1. Conservation

  2. Energy

  3. Force

  4. Motion

The correct answer is: Energy

Energy is the ability to do work, so it is the most suitable term out of the choices provided. Conservation (A) refers to the preservation or prevention of damage, which is not related to the ability to do work. Force (C) is a push or pull on an object, and while it may cause work to be done, it is not interchangeable with energy. Motion (D) is the movement or change in position of an object, and is also not synonymous with the ability to do work. Therefore, the best answer is energy.
