Section 1: Basic Energy Relationships1. Click/tap the Start button and observe the motion. View the barcharts and the velocity value as the coaster car moves. Completethe following paragraph by entering total mechanical energy(ME), kinetic energy (KE), and potential energy (PE). Thelabeled locations refer to the graphic at the right.As the coaster car rolls down the track from A to E, the________ values decrease and the _______ valueincrease and the ________ values remain constant. The_______ is greatest at point A and smallest at point E.However, the _______ is smallest at point A and largestat point E.Section 2: Hill Design2. Click/tap on the Bumps tab at the top of theInteractive. Then drag the grey circles to modify thetrack so that it looks like the track design at the right.Pay attention to the background grid to help with thedesign. Note that Dot G is at the same height as Dot E;make sure that the same is true of your final design.3. Run the simulation. Does the coaster car travel as highas point H? ___________ Give an explanation for whyit does or doesn't reach point H.
