This simulation (http://phet. colorado. edu/en/simulation/energy-skate-park - basics) shows how kinetic and potential energy are related, in a scenario similar to the roller coaster. Observe the changes in KE and PE by clicking on the bar graph boxes. Also try the three diferently shaped skate parks. Drag the skater to the track to start the animation. The bar graphs show how KE and PE are transformed back and forth. Which statement best explains what happens to the mechanical energy of the system as speed is increasing? a. The mechanical energy of the system increases, provided there is no loss of energy due to friction. The energy would transfomm to kinetic energy when the speed is increasing. b. The mechanical energy of the system remains constant provided there is no loss of energy due to friction. The energy would transform to kinetic energy when the speed is increasing c. The mechanical energy of the system increases provided there is no loss of energy due to friction. The energy would transform to potential energy when the speed is increasing. d. The mechanical energy of the system remains constant provided there is no loss of energy due to friction.
