Kinetic Energy Gain Formula
The following equation is used to calculate the Kinetic Energy Gain .
KEg = .5 * dV^2 * dm
Variables:
- Where Keg is the Kinetic Energy Gain (Joules, J)
- dV is the gain in velocity (m/s)
- dM is the gain in mass (kg)
How to Calculate Kinetic Energy Gain?
The following two example problems outline the steps and information needed in order to calculate the Kinetic Energy Gain .
Example Problem #1:
- First, determine the gain in velocity (m/s). In this example, the gain in velocity (m/s) is measured to be 4.
- Next, determine the gain in mass (kg). For this problem, the gain in mass (kg) is calculated to be 8.
- Finally, calculate the Kinetic Energy Gain using the formula above:
KEg = .5 * dV^2 * dm
Inserting the values from above and solving the equation with the imputed values gives:
KEg = .5 * 4^2 * 8 = 64 (Joules, J)
Example Problem #2:
Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:
gain in velocity (m/s) = 9
gain in mass (kg) = 3
Entering these values into the formula or calculator above gives us:
KEg = .5 * 9^2 * 3 = 121.5 (Joules, J)
