Understanding Potential and Mechanical Energy

WebAll we have to worry about is the kinetic energy and the gravitational potential energy; when we add these up at the top and bottom they should be the same, because mechanical energy is being conserved. At the top: PE = mgh = (20) (9.8) (100sin30°) = 9800 J KE = 1/2 mv 2 = 1/2 (20) (2) 2 = 40 J Total mechanical energy at the top = 9800 + 40 ... WebAt the bottom of the cupboard the suitcase will have lost all its potential energy and its potential energy will be equal to zero. E P = mgh = (1 kg )(9 ;8m s 2)(0 m ) = 0 J This example shows us that objects have maximum potential energy at a maximum height and will lose their potential energy as they fall. 444 Physics: Mechanics WebIf gravitational potential energy is the potential of an object to do work as a result of its position in a gravitational field, why is it equal to mgh?
