# How To Calculate Impact Force

### How to Calculate Force of Impact Sciencing

Apr 29, 2018 During an impact, the energy of a moving object is converted into work, and force plays an important role. To create an equation for the force of any impact, you can set the equations for energy and work equal to each other and solve for force. From there, calculating the force of an impact is relatively easy.

Apr 18, 2019 Force is the "push" or "pull" exerted on an object to make it move or accelerate. Newton's second law of motion describes how force is related to mass and acceleration, and this relationship is used to calculate force. In general, the greater the mass of the object, the greater the force needed to move that object.
