The accelerometer measures motion. It measures motion in varying degrees
from slight motion to extreme motion. The accelerometer also uses gravity to
determine the direction of motion. Motion is not just from side to side or up
and down. Rotating the micro:bit is also considered as motion.
A great example of an application of accelerometers are airbags in modern
vehicles, where an accelerometer is used to detect the rapid deceleration of a
vehicle. If rapid deceleration were to occur, the airbags are deployed.
Accelerometers can also be used to detect when an object is in free fall, which
is when only the force gravity is acting upon an object. If you were to throw
a ball directly into the air, free fall would begin as soon as the ball begins its
decent after the acceleration from your throw has subsided.
