The evidence that an object has energy can be observed through its ability to do work or cause a change in its surroundings. For example, a moving object has kinetic energy, while a stretched spring has potential energy. On the other hand, an object that is at rest and not interacting with its environment may be considered to have no energy.
Energy and work have the same units (joules) because work is the transfer of energy from one form to another. When work is done on an object, energy is either transferred into or out of the object. This transfer of energy is what causes change in the object's state.
No, potential energy is not in motion. Potential energy is the energy stored in an object due to its position or configuration in a force field. When the object is in motion, it will have kinetic energy, which is the energy of motion.
If an object falls twice as far, it acquires twice as much potential energy due to the increase in height. The increase in potential energy is directly proportional to the distance the object falls.
When you lift an object, you are transferring energy in the form of work done against gravity. This added energy gives the object potential energy, which is stored energy due to its position relative to the earth's surface.
I don't think a falling object is storing energy. In an ideal case, its potential energy is changing into kinetic energy, but the total energy is the same. In the real world, it loses some energy to air friction. The energy loss becomes heat and raise its temperature and the surrounding air. The energy loss is leaving the object permanently.
They have potential energy
The only sure way to establish that would be to measure anddemonstrate that the sum of the object's(potential energy) + (kinetic energy) + (internal heat energy)is not changing.
I think you mean kinetic energy. That is energy of a moving object.
I don't think there is any firm evidence that such a "psychic energy" even exists.

Potential
No, potential energy is not in motion. Potential energy is the energy stored in an object due to its position or configuration in a force field. When the object is in motion, it will have kinetic energy, which is the energy of motion.

It means that if an object is elevated to a higher position, it has more energy. It takes work to push the object up against Earth's gravitation; this work can be recovered when the object goes down again. While it is up, you can think of energy being saved in the object due to its position. More precisely, the energy is saved in the system Earth-object.
I think it is the kinetic and potential energy but i am not sure
