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.
