Enter the mass (kg), the initial height (m), and the final height (m) into the calculator to determine the Increase in Potential Energy.

## Increase in Potential Energy Formula

The following equation is used to calculate the Increase in Potential Energy.

dPE = m*g*(H2-H1)

• Where dPE is the Increase in Potential Energy (J)
• m is the mass (kg)
• H1 is the initial height (m)
• H2 is the final height (m)
• g is the acceleration due to gravity (9.81 m/s^2)

## How to Calculate Increase in Potential Energy?

The following example problems outline the steps and information needed to calculate the Increase in Potential Energy.

Example Problem #1

1. First, determine the mass (kg). In this example, the mass (kg) is determined to be 4 .
2. Next, determine the initial height (m). For this problem, the initial height (m) is measured to be 10 .
3. Next, determine the final height (m). In this case, the final height (m) is found to be 20.
4. Finally, calculate the Increase in Potential Energy using the formula above:

dPE = m*g*(H2-H1)

Inserting the values from above and solving the equation yields:

dPE = 4*9.81*(20-10) = 392.4 (J)

Example Problem #2

Using the same method as above, first, we need to measure or determine the variables required by the equation. For this example problem, these are provided as follows:

mass (kg) = 5

initial height (m) = 20

final height (m) = 30

Enter these given values into the calculator or above yields:

dPE = 5*9.81*(30-20) = 490.5 (J)
