A2 Physics - Circular Motion & Oscillations

Circular Motion 1

10 marks over 5 questions.
Write superscript as a normal number
e.g. ms-1 = ms-1

Each question is about a different scenario where circular motion is present. To help you practice the questions faster, you are simply given the values, without a special explanation.

You are given: v = r ω
1. Find the linear velocity when r = 3 m and ω = 1 rad s-1. [2]
2. What is the angular velocity ω when v = 30 ms-1 and r = 20 m? [2]
3. Find the tension where m = 5 kg, v = 10 ms-1 and r = 1 m. [2]
4. What is "v" to 2.d.p when m = 20 kg, F = 2.0 kN and r = 5 m? [2]
5. Find the centripetal force when v = 5 ms-1 and r = 10 m. [2]
