Cambridge IGCSE Physics 0625: Acceleration | Unit 1 | L5

This lesson covers syllabus section 1.2 (Supplement) — defining acceleration as change in velocity per unit time, recalling and using a = Δv/Δt, and knowing that a deceleration is a negative acceleration.

PowerPoint includes:
• Retrieval starter with answer slide
• Direct Instruction (I Do) — acceleration defined; the acceleration equation; rearranging the equation; why the sign matters for deceleration; full worked example
• Guided Practice (We Do) — three guided calculations
• Check for Understanding — MCQs with separate answer slides
• Independent Practice (You Do) — the lesson worksheet
• Exit Ticket

Worksheet includes:
• Formula box: a = Δv / Δt
• 12 exam-style questions covering acceleration from rest, between two speeds, deceleration as a negative value, finding final speed and time, free fall with g = 9.8 m/s², and acceleration in circular motion
• Stretch question: stopping time for a decelerating train, and a comparison with a second train that stops in half the time
• Full mark scheme on a separate page (32 marks)
