AQA A Level PE Biomechanics – Angular Motion Lesson 2: Angular Displacement, Velocity & Acceleration

A complete, ready-to-teach AQA A Level PE lesson on measuring rotation: radians, angular displacement, angular velocity and angular acceleration, with modelled calculations.

How do we measure how fast a gymnast is rotating? This lesson gives students the definitions, units and calculations for angular motion that the AQA specification requires (7582, 3.2.2.4) — and makes the maths feel manageable, using the somersault, the discus and the high bar.

Every angular quantity is taught alongside its linear partner, which students retrieve in the Do Now. The radian is made physical with a Feel It activity where students turn on the spot through 1.57 rad, 3.14 rad and finally one radian (1 rad = 57.3°), before converting between degrees and radians.

Calculations follow a strict I do → We do → You do structure (formula → substitute → calculate → unit):

• Angular velocity on the high bar (handstand to hang)
• A diver’s quarter turn — with the classic “forgot to convert to radians” trap built in
• Angular acceleration of a discus thrower across the circle
• Independent practice, a rearrangement challenge and a deceleration extension

Misconceptions are tackled head-on: angular distance vs angular displacement, spot-the-error student answers, and a hinge question on constant angular velocity. The lesson closes with a multi-part exam question (definition, calculation and a synoptic link back to torque and Newton’s second law) with mark-by-mark feedback.

What’s included

• Teacher PowerPoint (22 slides) built on the Exam Vista teaching framework, with detailed speaker notes including every answer and common error
• Student Workbook (7 A4 pages, editable Word) — conversion tables, calculation frames, spot-the-error and exam practice
• Teacher Answer Version — an exact copy of the workbook with every answer and worked calculation in green
