Energy can be demonstrated through various forms such as heat, light, sound, or motion. For example, the energy in food is converted into heat and mechanical energy by our bodies to allow us to move and perform tasks. In a simple experiment, energy can be shown by lighting a bulb using a battery or by swinging a pendulum.
The person jogging with her dog demonstrated kinetic energy, which is the energy of motion. As the person moves and the dog runs alongside, both have kinetic energy that comes from their movement.
The kinetic energy is demonstrated by the motion of a pendulum swinging back and forth. As the pendulum moves, it converts potential energy (from its raised position) into kinetic energy (from its motion).
The solar panel harnesses solar energy and converts it to electricity. The wind turbine converts wind energy into mechanical power and then electricity. The battery stores electrical energy for later use.
In a physical system, the conservation of momentum is demonstrated when the total momentum before an event is equal to the total momentum after the event, as long as no external forces are present. This means that the total momentum of the system remains constant. Similarly, the conservation of kinetic energy is demonstrated when the total kinetic energy before an event is equal to the total kinetic energy after the event, again assuming no external forces are involved. This means that the total kinetic energy of the system remains constant. Both principles are fundamental in understanding the behavior of physical systems and are often used to analyze and predict the outcomes of various interactions.
The motion of a swinging pendulum demonstrates kinetic energy, which is the energy of motion. As the pendulum swings back and forth, its kinetic energy changes as it moves between potential energy at the highest point of the swing.

uses energy
The obvious relationship demonstrated by a food chain is the transfer of energy and nutrients from one organism to another. It shows how energy flows from producers (plants) to consumers (animals) through various trophic levels.
The first chain reaction was demonstrated in the Chicago 'pile', in 1942.
The battery chemical energy transforms into electric energy that is demonstrated as light.
It demonstrated the potential energy contained in matter.
Nowadays it is demonstrated by Noether's Theorem. Note that this involves some fairly advanced math. The basic assumption (for the Theorem) is that the laws of physics don't change over time. Another kind of reasoning is by observation: in all known processes, energy is always conserved.

The thermal energy output of the new engine was inefficient, as the thermometer quickly demonstrated.
