UNIT 04 : ROTATIONAL AND CIRCULAR MOTION

Rotational and Circular Motion is part of the 20% Physics allocation of your 36-question paper, and this section covers its foundational angular kinematics concepts.

What this chapter covers:

• Angular displacement
• Revolution, degree and radian
• Angular velocity
• Relation between linear and angular variables
• Relation between linear and angular displacements
• Relation between linear and angular velocities
• Relation between linear and angular accelerations

This chapter is a mix of conceptual definitions and calculation-based problem-solving, since it builds the core vocabulary of rotational motion while also requiring comfort converting between linear and angular quantities. Given the PMDC’s 15% easy, 70% moderate, 15% difficult split, expect most questions here to test careful application of formulas like S = rθ, v = rω, and a = rα rather than pure recall.

Why this practice set helps:

• Covers every subtopic the PMDC curriculum identifies, plus the supporting concepts textbooks present alongside them
• Every question includes a full explanation of why the correct answer is right and why each other option is wrong
• Built to help you learn faster than passive reading, with nothing the exam may draw from left untouched

Work through this set attentively, and you build both the definitional precision and calculation speed this chapter demands.
