... Explain what is meant by angular displacement and speed. State the equations relating angular speed to (a) linear speed; (b) frequency and (c) period. Calculate the angular speed and rotational frequency for an object travelling at 5.0ms-1 around a circle of radius 6 cm. Explain why motion along a c ...
