Potential energy is the energy stored within an object, not in motion but capable of becoming active. It depends on an object’s position, arrangement, or state within a field or system. In this article, we are going to learn about various real-life applications of Potential Energy.
What is Potential Energy?
Potential energy is defined as the energy stored by an object due to its arrangement, state or position. It is a scalar quantity, which means it has magnitude but no direction. It is measured in Joules and can be converted into other forms of energy, such as kinetic energy.
For instance, when you lift a book off the ground, you give it gravitational potential energy. The higher you lift it, the more energy you store. If you let the book go, it falls, and the stored energy changes to motion, which is kinetic energy. This shows how potential energy can change into another form of energy.
