Fill in the blаnk with the cоrrect wоrd fоr eаch definition. Be cаreful with your spelling. [work] is the force times the displacement on an object that tracks action on an object. The ability for an object to do work, or the budget to allow work, is called [energy]. If work is done to change the position of an object, especially if it against a force, will change [potential_energy]. If work is done to change the velocity of an object, that changes the [kinetic_energy].
