  • How to Calculate Load Force | Sciencing

    This basic principle is what is used to calculate load force, which is the force that opposes that entity. Any time one does work, such as lifting a coffee mug off a table or pushing a ball up a hill, energy is transferred from the entity to the object, causing a desired effect. The object's mass is the resistance acted upon—its load force. Pick something up—really, anything. It has a mass ...
