# How to solve potential energy problems?

Jul 22, 2022

There are many ways to solve potential energy problems, but one of the most common methods is to use the equation PE = mgh. This equation states that the potential energy (PE) of an object is equal to its mass (m) multiplied by the acceleration due to gravity (g) multiplied by the height (h) of the object.

To use this equation, you must first determine the mass, acceleration due to gravity, and height of the object. The mass is usually given in kilograms (kg), the acceleration due to gravity is usually given in meters per second squared (m/s^2), and the height is usually given in meters (m). Once you have these values, you can plug them into the equation and solve for the potential energy.

For example, let’s say you have a 2 kg object that is 1 m off the ground. The acceleration due to gravity is 9.8 m/s^2. To find the potential energy of the object, you would plug these values into the equation and solve as follows:

PE = mgh

PE = (2 kg)(9.8 m/s^2)(1 m)

PE = 19.6 kg·m/s^2

The potential energy of the object is 19.6 kg·m/s^2.
