A circular platform rotates horizontally about a fixed vertical central axis with a constant, non-zero angular speed \(\omega\). A small block rests on the platform at a fixed radial distance \(r\) from the axis and does not slip. An accelerometer attached to the block measures a constant, non-zero linear acceleration. Which of the following statements best explains why the block experiences a non-zero linear acceleration while the platform rotates at a constant angular speed?
