PPT-Work and Power Notes Work is done when a net force acts on an object and the object moves

Work is the product of the force on an object and the distance through which the object is moved the quantity force distance Work If the force is constant and the motion takes place in a straight line in the direction of the force the work done on an object by a net force is the product of the force and the distance through which the object is moved.
