- a 1 kg flower pot has 20 J of energy when resting on a window ledge. how high is the window from the groud? take the ground to be the reference level 0.We know from the reading that it is possible to move the same object two different distances and still do the same amount of work. Let's consider an example in which Jane pushes a block of ice up an incline while Kip lift the same block of ice vertically to the top of the same incline. See the figure below. (look at picture) We will assume that there is no friction between the surface of the incline and the block of ice. Both of these situations will require the same amount of work and that the result of lifting the ice block to some height imparts potential energy to the ice. In this activity, we will make various calculation to help us better understand the relationship between work and potential energy and the idea of conservation of energy. For this activity we will assume that the mass of the ice block is 5.6 kg and the vertical height of the incline is 2 m. This is the vertical distance that Kip must lift the block of ice. We will assume that the acceleration due to gravity is 10…Non-conservative work is...(select all that apply) made by a non-conservative force acting on an object over some parallel distance transforms mechanical energy into deformations or thermal energy or sound removes mechanical (kinetic and potential) energy from the system depends on the total path traveled and not just the displacement
