Kinetic energy is the energy the body possesses due to its motion. Kinetic energy is a kind of mechanical energy, as well as potential energy. All bodies that move linearly or rotate possess a certain kinetic energy.
Potential energy is the energy that an object has due to its position relative to another object. When we stand on the top of the building, we have more potential energy than when we are at the bottom, because the earth is attracted by the force of gravity.
When the body falls, it at the beginning of the fall has potential energy due to the force of gravity, and therefore falls, and then the potential energy turns into a kinetic, because the body moves in the fall.
When we kick the ball upwards, it moves upward, because it has kinetic energy, until it stops at one point, since there is no kinetic energy of motion, and only at that moment the kinetic energy turns into a potential, at that moment the ball is stopped, until it starts to fall again.

False; stop sympathizing with Delmar and to withhold any sort of positive
reinforcement to his pain behaviors would make him bear the pain.
How positive reinforcement works?
Positive reinforcement in operant conditioning refers to the addition of a reinforcing stimulus after a behavior that increases the likelihood that the behavior will occur again in the future. An action's response or behavior will get stronger if a positive result, circumstance, or reward follows it. Here Delmar needs positive reinforcement for reduction in pain.
Positive reinforcement's impact on motivation is another factor contributing to its appeal as a teaching strategy. Positive reinforcement may provide you the boost in motivation you need to accomplish the goals you set, whether you are using it on your staff to reward good work or on yourself to work toward personal goals. Delmar should use positive reinforcement against his pain behaviour.
