1 Physics and Astronomy Outreach Program at the University of British Columbia Physics and Astronomy Outreach Program at the University of British Columbia Multiple-Choice Questions TRANSPORTATION Energy Use in Cars 2: Constant Speed Cruising

2 Physics and Astronomy Outreach Program at the University of British Columbia Physics and Astronomy Outreach Program at the University of British Columbia Energy in Cars 2 How could we reduce the energy cost of travelling at constant speed? 1.Design a car with a more long & thin shape 2.Drive more slowly 3.Make the car much lighter 4.Inflate the tires 5.Get a regenerative braking system

3 Physics and Astronomy Outreach Program at the University of British Columbia Physics and Astronomy Outreach Program at the University of British Columbia Energy in Cars 2 How could we reduce the energy cost of travelling at constant speed? 1.Design a car with a more long & thin shape 2.Drive more slowly 3.Make the car much lighter 4.Inflate the tires 5.Get a regenerative braking system

4 Physics and Astronomy Outreach Program at the University of British Columbia Physics and Astronomy Outreach Program at the University of British Columbia Energy in Cars 2 In Energy in Cars 2: Constant Speed Cruising the amount of energy consumed is related to the car’s velocity (v) and its size (the volume of the cylinder of air that it disturbs (proportional to A car )). In Energy in Cars 3 energy savings from tire inflation is explored.
