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.
