What is the formula for potential energy?
Potential energy is the energy that is stored in the object. Under the correct conditions, this energy can be released as kinetic energy or as the energy of movement. Many different types of objects have energy stored as potential energy, including fuel, food and springs. The potential energy of the object can be calculated using the formula for potential energy.
There are different types of potential energy based on how energy is stored. Food and fuel contain the energy of chemical potential, while stretched elastic belts have elastic potential energy. The formula for the potential energy used depends on the type of energy stored. In this article, the formula for the potential energy that is discussed is for gravitational potential energy. Gravitational potential energy is the potential energy of the object due to the height of the object above a certain reference point that is usually of the Earth's surface.
to calculate the potential energy energy, formal potential energy (PE)It is PE = MGH , where M means the weight of the object in kilograms (kg), G is the gravitational force of the field and h is the height of the object in meters (m). Rarely, the object is raised sufficiently high enough to change the gravitational field, so that 9.8 m/s2 (meters per second to the other) is almost always used in the formula for potential energy. In some cases, GPE is used instead of PE to show that the energy of gravitational potential is calculated.
For example, the weight of 25 kg is raised 5 m above the ground. Compared to the ground, it is possible to calculate the change in potential energy by replacing the numbers to the equation as such: PE = MGH = 25 x 9.8 x 5 = 1225 joules (J). Joules are units used to measure energy and are named after scientists named James Joule. In the mid -18th century, Joule carried out a large number of experiments to prove warmth and energy.
From the previous example, it was found thatWeight has 1225 J stored energy or potential energy. This means that if the weight was released, this stored energy would be converted into kinetic energy when it dropped to the ground. Energy is preserved - not created or lost. As a result, its kinetic energy would be the same as its potential energy or 1225 j
