06-12-2020· 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.

05-11-2018· If I were to hit an anvil with a hammer (let's say a 1 kg hammer at 1 m/s) how would the force of the impact be calculated? So, where I'm at with this is that I know the deal with f = mv, so the force would be equal to 1N/s. My problem is with the time that it takes for the energy to be transferred from the hammer to the anvil.
