HERE’S HOW IT CONTINUES

Time trials

Test car A clearly moves faster than test

car B. Using the speed calculation here,

you will see that car A moves about

twice as fast as car B. Changing the gears

changed the speed of the car. It also

changed the torque. Move on to the next

experiment to learn more.

3. Now, switch the red and the blue gears

on your test car to make a different ver-

sion of the car. We will call this new ver-

sion “test car B,” and the original ver-

sion “test car A.” You will have to remove

the motor and rear axle in order to

switch the gears, and then replace them

again.

4. Like you did before with test car A, use the

stopwatch or timer to time how long it

takes for test car B to travel between the

start and end points. Record the time

below.
