A.2.26—Angular and linear speed Topic Practice
Practise converting between angular speed, frequency, period and linear speed for rotating objects, including rolling and orbiting situations.
How this is tested
- use ω = 2πf or ω = 2π/T to convert revolutions per second or period into angular speed
- apply v = rω to find the linear speed of a point on a wheel, pulley, bottle or satellite path
- compare points on the same rotating disc by linking larger radius to greater linear speed at the same ω
