Part AThe work-energy theorem states that a force acting on a particle as it moves over a changes the energy of the particle if the force has a component parallel to the motion. Choose the best answer to fill in the blanks above:distance / potentialdistance / kineticvertical displacement / potentialnone of the abovePart BTo calculate the change in kinetic energy, you must know the force as a function of . The work done by the force causes the kinetic energy change. Choose the best answer to fill in the blank above: energyPart CTo illustrate the work-energy concept, consider the case of a stone falling from xi to xf under the influence of gravity. Using the work-energy concept, we say that work is done by the gravitational , resulting in an increase of the energy of the stone.
