calculate hammer crusher impact force

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 ...
