Gravitational potential energy, __________ potential energy and _______ energy are types of mechanical energy . When gravity acts to slow an upward-moving object, the work done by gravity is ________ because the force of gravity points ________to the direction of motion. In this case the work done by gravity points ____________ to the direction if motion. in this case the work done by gravity converts kinetic energy in the object to _______ potential energy. When gravity acts to speed up a downward-moving object, the work done by gravity is _______ because the force of gravity points in the same direction as motion. in this case the work done by gravity converts _______ potential energy into __________ energy The work done by gravity always moves energy between potential and kinetic forms, so gravity is a __________ force that does __________ work. When you lift an object at a constant speed you apply a force over some distance, which means you do ________. That _________ transferred chemical potential energy in your body to ________ potential energy. Chenmical potential enerty is not a type of mechanical energy. so the work you did was ___________ and the force you applied was a ________ force
