ACTIVITY #5: RC CAR ACCELERATION STUDY
This activity demonstrates how to use the program DatalogAcceleration.bs2 from the
previous activity to analyze the acceleration forces on a radio-controlled (RC) car during
a variety of maneuvers.
acceleration forces can be used to track and plot the car's velocity and position. Although
the actual equipment and calculations are somewhat more involved, deriving position
from successive acceleration measurements is a component of the inertial guidance
systems employed in rockets and spaceships. These systems use a combination of the 3-
