A joule is simply a unit to measure energy. Examples of energy include gravitational potential energy, kinetic energy, sound energy, light energy, elastic energy, nuclear energy.
It is different because gravitational potential energy is when something is getting pulled by gravity and potential energy is stored energy which means that it is not moving and the energy is not getting released as gravitational energy is.
Potential energy.
With potential energy, what matters is the difference in potential energy, not the energy in absolute terms. To simplify calculations, the gravitational potential at infinity is arbitrarily set to zero. This gives objects that are nearer than infinity (to any object that attracts them gravitationally), a negative potential energy.With potential energy, what matters is the difference in potential energy, not the energy in absolute terms.

Gravitational + Potential = 100 If you have 67 J of potential energy your gravitational energy would be 33 J.

Elastic energy, for example, a stretched spring.
The energy stored in a stretched elastic is potential energy, specifically elastic potential energy. When the elastic is stretched, work is done to stretch it, and this work is stored as potential energy in the elastic material.
Elastic potential energy is stored in elastic objects when they are stretched or compressed. This energy is potential energy that can be released when the object returns to its original shape.
A stretched rubber band contains elastic potential energy. Compressed springs store elastic potential energy. A bent bow with a drawn string has elastic potential energy.
Elastic cars work by converting elastic potential energy into kinetic energy. The most potential energy, the more kinetic energy.
A compressed spring has potential energy stored in the form of elastic potential energy. This potential energy is ready to be released as kinetic energy when the spring is allowed to expand and return to its natural state.
Elastic potential energy refers to the potential energy stored as a result of deformation of an elastic object. An example of this is a spring, which springs back before it has gained elastic potential energy. After a spring gains elastic potential energy, it will be deformed.
Elastic force is the force exerted by a stretched or compressed elastic material to return to its original shape. Elastic potential energy is the energy stored in an elastic material when it is stretched or compressed. The elastic force is responsible for restoring the material to its original shape, converting the stored elastic potential energy back to kinetic energy.
No.
Some non-examples of elastic potential energy include gravitational potential energy, kinetic energy, and thermal energy. These types of energy are different from elastic potential energy as they are not associated with the deformation or stretching of an elastic material.
A catapult has elastic potential energy when the elastic has been pulled back. This potential energy is stored in the stretched elastic material. When the catapult is released, this potential energy is converted into kinetic energy as the projectile is launched forward.
