Standard Test Methods for Determining the Izod Pendulum
Energy is defined as the ability to do work During an impact an object s energy is converted into work The energy of a moving object is called kinetic energy and is equal to one half of the object s mass times the square of its velocity KE = 0 5 × m × v^2 When thinking about the impact force of a falling object you can calculate the energy of the object at its point of impact if you
