COMSATS Physics — Circular and Rotational Motion
Circular and Rotational Motion is part of the Physics section of the NTS NAT-IE test COMSATS admits on (10 of the 90 MCQs). It breaks into 3 subtopics, and we hold 26 NAT-pattern practice MCQs on it, each with a written explanation. Tap a subtopic below to practise just that.

Circular and Rotational Motion MCQs from the NAT-pattern papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · COMSATS Past Paper 07 · Circular and Rotational Motion
A body moves in a circle of fixed radius. If its speed is doubled, the centripetal force needed becomes:
- A.four times as large
- B.half as large
- C.twice as large
- D.unchanged
Show answer
Answer: A. four times as large — F = mv²/r; doubling v multiplies F by 4.
- Q2 · COMSATS Past Paper 06 · Circular and Rotational Motion
The SI unit of angular velocity is:
- A.m/s²
- B.rad/s
- C.revolution
- D.m/s
Show answer
Answer: B. rad/s — Angular velocity = angle ÷ time: radians per second.
- Q3 · COMSATS Past Paper 05 · Circular and Rotational Motion
A geostationary satellite has an orbital period of:
- A.24 hours
- B.1 hour
- C.365 days
- D.12 hours
Show answer
Answer: A. 24 hours — It turns with the Earth, so its period equals one day, 24 hours.
