Answer
Heat
Explanation
## Step1: A force is a push or pull upon an object resulting from the object's interaction with another object. These interactions result in different types of forces. ## Step2: Friction is a force that resists the motion of two surfaces in contact. ## Step3: Elastic force is the force exerted by an object trying to restore its original shape after being deformed. ## Step4: Reaction force is the force that is in the opposite direction to an action force. It is part of the action-reaction force pair described by Newton's third law of motion. ## Step5: Heat, however, is not a force. It is a form of energy that is transferred between objects or systems due to a temperature difference.
