How does an energy source (solar or
battery) affect the speed of a four
wheeled model car?
Build a homemade car with a pre built
motor. Operate the car using both
solar and battery powered energy
sources to test the speed and duration
of motion.
Solar panel, prebuilt direct current
motor, (1) large pulley, (1) small
pulley, electrical tape, (6) screws, (2)
axels, (4) wheels, drinking straws cut
to 1 cm each, 15.24 cm. wooden
board, switch, battery pack, and (2)
AA alkaline batteries (1.5 volts each).
There are different types of energy
sources, some are more efficient than
others, and some last longer than
others. But there is one that isn’t that
efficient, but it isn’t limited. There are
many cars moving away from fossil
fuels, like Chevy Volt and Porsche 918
