Impact Energy Formula
The following equation is used to calculate the Impact Energy.
Ei = 1/2*m*Vi^2
- Where Ei is the Impact Energy (Joules)
- m is the mass (kg)
- Vi is the velocity at impact (m/s)
What are the units for Impact Energy?
The most common units for Impact Energy are Joules.
How to Calculate Impact Energy?
The following example problem outlines the steps and information needed to calculate the Impact Energy.
First, determine the mass. In this example, the mass is determined to be 51 (kg).
Next, determine the velocity at impact. For this problem, the velocity at impact is measured to be 3 (m/s).
Finally, calculate the Impact Energy using the formula above:
Ei = .5*m*Vi^2
Inserting the values from above and solving the equation with the imputed values gives: Ei = .5*51*3^2 = 229.5 (Joules)
