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

Work is done when a force acting on a body displaces it in the direction of a force For instance, the work done by a moving object equals 1 Joule when a force of 1 Newton is applied over 1 meter of distance Since the applied force can be negative or positive, therefore, work can be negative or positiveW= Fd Work equals the applied force times displacement W= F g d The applied force equals the weight of the object (F = F g) W= mgd The weight of the object equals its mass times the acceleration due to gravity (F g = mg) W= mgh The displacement over which the work is done equals the height of the lift (d = h)Can Work Be Negative?
