Potential Energy and Kinetic Energy WorksheetDefine Potential Energy : _____________________________________________________________________PE = mghm = ______ units: _____g = ________ units: _____h = ________ units: _____Define Kinetic Energy : _______________________________________________________________________KE = (1/2)mv2m = ______ units: _____v = ________ units: _____units for energy : _________1) A 21.0 kg box is sitting on top of a 3.0 meter shelf in a store. How much potential energy (PE) does it have?

A 50.0 kg washing machine falls from a 16.0 meter roof top. 2) What is the PE of the washing machine before it falls?3) Does the PE of the washing machine A) increase, B) decrease, or C) stay the same as it falls?What type of energy is the PE converted into as the washing machine falls?4) How much Kinetic Energy (KE) will the washing machine have just before it hits the ground?5) How much KE does a 1500 kg car traveling 20 m/s have?Our turkey from the momentum worksheet is now sitting in the hunter's oven, which is 0.25 meters above the ground. Once cooked for the meal, he has a mass of 5.3 kg. The hunter gazes at the view from his back yard.6) What is the turkey's potential energy as he sits in the oven?A gas leak in the hunters house causes the oven to explode, which sends the perfectly roasted turkey flying out the window at a velocity of 25.0 m/s and a height of 1.5 meters.7) What is the KE of the turkey?8) What is the new PE of the turkey?9) What is the total Mechanical Energy of the turkey? (ME = KE + PE)The hunter is standing dangerously close to a 1,156 meter cliff as he notices the turkey flying towards him. The hunter has a mass of 80 kg and moves away from the cliff (towards the turkey) at a velocity of -3.0 m/s.10) What is the PE of the hunter? (Use the height of the cliff)11) What is the KE of the hunter?12) Does the hunter A) catch the turkey and have his dinner or B) does the turkey have his revenge by sending the hunter falling off the cliff to his death? (Compare the momentum of the turkey to the momentum of the hunter)Mr. Robinson demands that you draw a turkey.
