1. When energy is transferred from one object to another, the receiving object gains energy, which can result in changes such as movement, increased temperature, or deformation. The total energy remains constant, following the law of conservation of energy.

  2. The toy car and balloon examples illustrate energy conversion: in the toy car, stored elastic potential energy in the spring converts to kinetic energy, while in the balloon, stored air pressure converts to kinetic energy when released.

  3. The relationship involves energy transfer: the object doing work loses energy, while the object on which work is done gains energy, resulting in a change in motion, position, or state of the receiving object.
