feet, we will free-fall. It is that we have a trend to falling, which is called the
acceleration of gravity written as g in formulas.
We measure coordinate of x, y and z directions. With these three values, we could get
the direction of accelerations. If there is only acceleration of gravity, the direction is
downward. We keep measuring values of x, y and z coordinates to get the acceleration
of micro:bit, and detect actions like shake, tilt and so on
