published by the UCLA Department of Physics and Astronomy
written by Martin Simon

This item is an interactive lecture demonstration (ILD) that helps students understand the Law of Inertia as it relates to circular motion. It features a pie plate with a wedge cut out. A metal ball is then spun around the rim of the plate. The inward force of the rim keeps the ball in circular motion until the rim ends, when the ball flies off in a straight line, obeying Newton's First Law. The action is animated to clearly illustrate how the demonstration should appear in the physics classroom.

This item is part of a much larger collection of multimedia teaching resources which includes a database of ILD's, simulations, and video clips, compiled by the UCLA Department of Physics and Astronomy. SEE RELATED ITEMS BELOW for a link to the full collection.

Please note that this resource requires Java Applet Plug-in, or Flash.

Next Generation Science Standards

Disciplinary Core Ideas (K-12)

Forces and Motion (PS2.A)

The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion. (6-8)

AAAS Benchmark Alignments (2008 Version)

4. The Physical Setting

4F. Motion

6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.
6-8: 4F/M3b. If a force acts towards a single center, the object's path may curve into an orbit around the center.

This resource is part of a Physics Front Topical Unit.

Topic: Dynamics: Forces and Motion
Unit Title: Newton's First Law & Inertia

What would happen if an object in circular motion suddenly loses its net centripetal force? Teachers can easily set up this demo to show students that Newton's Law of Inertia will govern the situation, and the object will fly off in a straight line tangential to the circular path.
