How do you xxplain potential energy?

Answer 1

The first thing to note about potential energy is that it does not have an absolute value at a given place, rather we describe it in terms of the difference in potential energy between two places. Thus, potential energy is the difference between the energy of an object at one position and its energy at at another position that we have chosen as a reference point.

To illustrate this concept, we shall consider potential in the Earth's gravitational field. Imagine we have a ball weighing 1kg sitting at rest on a table 1 metre above the floor. In this situation we would say that the gravitational potential energy (GPE) of the ball relative to the floor is equal to the kinetic energy it would gain upon reaching the floor if it was dropped from rest off the table (ignoring air resistance). In this case the ball's GPE relative to the floor is roughly 192.5 J.

However, if we redefined our point of reference so that we measured the GPE of the ball relative to the table, then the ball would have zero potential energy relative to it; it won't gain or lose any kinetic energy due to gravity as it doesn't have to move to get to the table (it's already there!) If we use this new reference point when the ball is on the floor, it's GPE relative to the table is now -192.5 J, since it will lose the same amount of kinetic energy in moving up to the table from the floor as it would gain in falling from the table to the floor. i.e. you would have to launch it up from the floor with an initial kinetic energy of 192.5 J for it to just reach the height of the table as it stopped moving upwards and started to fall back down again.

Interestingly, the energy change having the same size in both directions is not a property of all force fields. Only fields such as gravitational, electric, etc.. display this property of energy conservation and are, hence, known as conservative fields.

ANSWER2

Potential Energy is a scalar energy as different from a vector energy.

Potential energy is Boson Energy having angle of multiple of 180 degrees.

Vector energy is Fermion energy with add angle of 90 degrees.

Answer 2

Potential energy is the energy an object has due to its position or configuration. This energy is stored and can be converted into other forms of energy, such as kinetic energy, as the object moves or changes position. The amount of potential energy depends on the object's mass, height, and the force acting on it.
