B. Try the other cars. Does the mass of the car affect its final speed? No 2. Collect data: Find the final speed of a toy car in each situation. Leave the last column blank. Hill 1 Hill 2 Hill 3 Final speed Total height lost 40 cm 0 cm 0 cm 283.6 40 40 cm 30 cm 0 cm 283.6 40 60 cm 50 cm 20 cm 280.1 40 60 cm 0 cm 0 cm 343.1 60 60 cm 45 cm 0 cm 343.1 60 90 cm 75 cm 30 cm 343,1 60 3. Analyze: Look at the data carefully. Notice that it is organized into two sets of three trials. B. Did hill 2 have any effect on the final speed? no C. Label the last column of the table Total height lost . Fill in this column by subtracting the height of hill 3 from the height of hill 1. D. What do you notice about the Total height lost in each set of trials? 4. Draw conclusions: When there is no friction, what is the only factor that affects the What factors do not

Activity B: Energy on a roller coaster Get the Gizmo ready: Click Reset . Select the 50-g car. Check that the Coefficient of friction is 0.00. Set Hill 1 to 100 cm, and Hill 2 and 3 to 0 cm. Question: How does energy change on a moving roller coaster? 1. Observe: Turn on Show graph and select E vs t to see a graph of energy ( versus time. Click Play and observe the graph as the car goes down the track. Does the total energy of the car change as it goes down the hill? E )
2. Experiment: The gravitational potential energy ( U ) of a car describes its energy of position. Click Reset . Set Hill 3 to 99 cm. Select the U vs t graph, and click Play .
