17 Motion in A Circle

This Section is just the first part of periodic motion with respect to motion in a circle, It is really important you spend quite a lot of time working on the basic maths here as it underpins the simple harmonic motion. Don’t skip through the practice questions or practical work as it is crucial to doing the more tricky questions later…

Circular Motion and Angular Speed

So this is a cool experiment to show how angular speed is not the same as speed.

The wheel clearly is turning at different distances per second. (v = 2pir/T)

However, ...the angle that each part on the spoke turns per second is a constant. (omega = theta */t or omega = 2 pif

You can do this with a marker and stopwatch instead of the fancy gates!Show More
