Formula w=mgh
Formula w=mgh-Let us calculate the work done in lifting an object of mass m through a height h, such as in Figure 1If the object is lifted straight up at constant speed, then the force needed to lift it is equal to its weight mgThe work done on the mass is then W = Fd = mghWe define this to be the gravitational potential energy (PE g) put into (or gained by) the objectEarth systemThis is a separate property from that of inertia, so we give this property the name gravitational mass • is a measure of how much matter there is in
