Physics KS3/GCSE: Why do boomerangs come back?
Greg Foot finds out why boomerangs return to the thrower.
He explains that the shape of the boomerang is like a plane’s wing that generates lift, and that the spinning boomerang acts as a gyroscope.
Greg then explains how gyroscopes work and demonstrates the gyroscopic procession that results in a ‘hands-free’ bicycle turning and a correctly thrown boomerang moving in a curve to return to the person who threw it.
Students could investigate why an aerofoil generates lift and perform simple classroom experiments such as blowing over the top of a sheet of paper, when held hanging by two of the sheets corners to form an aerofoil shape.
These short films will be relevant for teaching physics and chemistry at both KS3 and KS4 in England, Wales and Northern Ireland and National 4/5 in Scotland.
