Objective: The objective of this lab is to compare the distance traveled  between using a ruler and using the LearnSmart program on the computer.

Measurements:
Diameter = .055 m
Circumference = 0.1728 m

Questions:
a) The wheel rotation (in degrees and in number of turns). How are the degrees that the wheel rotated related to the number of turns of the wheel?
b) The time it took for the wheels to turn (in seconds and milliseconds).  How are seconds related to milliseconds?
c) The distance the car moved.  How is the distance related to the number of turns?

Answers:
a) When the wheel rotates 360°, the wheel will rotate 1 time.
b) In 1 second or 1000 millisecond, the wheel rotated 546° or 1.516 times at a power level of 75, 75. At a power level of 50, 50, the wheel rotated .966 times in 1 second and at 25, 25, the wheel rotated .377 times in 1 second.
c) The circumference is the distance when the wheel turns once. C = .1728 m = 1 wheel turn.
