Revise CIE IGCSE Physics 1.2.4 Acceleration and deceleration with the question bank and revision guides.
Define acceleration as change in velocity per unit time; recall and use the equation a = ∆v / ∆t • Determine from given data or the shape of a speed–time graph when an object is moving with: (a) constant acceleration (b) changing acceleration • Know that a deceleration is a negative acceleration and use this in calculations
