Quick Answer: The Apparatus for Coriolis Force shows the Coriolis effect: a ball or object rolled across a rotating platform appears to curve sideways when seen from the rotating frame.
Last updated: October 2026
Key Features
Demonstrates the apparent sideways deflection of a moving object in a rotating system
Rotation speed and direction can be changed between runs
Introduces inertial and non-inertial frames of reference
Links to atmospheric circulation, ocean currents and the effects of Earth’s rotation

Use
Apparent deflection of a moving object on a rotating platform
Application
Coriolis force, rotating frame, circular motion and relative motion experiments
Once the platform turns at a steady speed, a ball is released across it from a chosen starting point and its path is watched from the rotating frame. Repeating at a different speed or in the opposite direction lets students compare the curved paths and relate the deflection to the motion and the rotation. Laboratories and colleges in Latvia, Montenegro, Samoa, Eritrea and Albania can buy the Apparatus for Coriolis force through an export order.
