Potential energy change is the amount of energy an object has due to its position or state. It represents the potential for work to be done.
Potential energy change is calculated by multiplying the mass of an object by the acceleration due to gravity (9.8 m/s^2) and the change in height (in meters). The formula is PE = mgh.
Some examples of potential energy change include a rollercoaster at the top of a hill, a pendulum at its highest point, a stretched rubber band, and a book on a high shelf.
Potential energy and kinetic energy are two forms of energy that are constantly interchanging. When an object has a high potential energy, it has the ability to do a lot of work. As the object moves and loses potential energy, it gains kinetic energy, which is the energy of motion.
Potential energy change can be useful in various ways, such as in the production of electricity from hydropower, in the functioning of a spring-driven clock, and in the launching of rockets into space. It also plays a crucial role in daily activities, such as when we use a slingshot or a bow and arrow.
