Motion in a circle

CIE-style questions assess angular quantities, centripetal acceleration, radial forces and vertical circles.

Objective question 1

One complete revolution is:

Objective question 2

The relation between tangential and angular speed is:

Objective question 3

Centripetal acceleration is directed:

Objective question 4

Centripetal force means:

Objective question 5

At minimum contact at the top of an inside vertical loop:

Structured question 1

A wheel rotates at 4.0 Hz. Calculate angular velocity.

Structured question 2

A 0.80 kg object moves at 6.0 m s⁻¹ in a circle of radius 1.2 m. Calculate the inward resultant force.

Structured question 3

Calculate the minimum speed at the top of a vertical loop of radius 2.5 m. Use g = 9.81 m s⁻².
