EDEXCEL A LEVEL MATHS – PAPER 3 MECHANICS
EXAM TRIGGER DECK Questions And Answers
2025/2026
A particle moves with constant acceleration - CORRECT ANSWER-Identify SUVAT
variables → choose equation with known values → solve.
Particle starts from rest - CORRECT ANSWER-u = 0 → simplify SUVAT equations.
Particle comes to instantaneous rest - CORRECT ANSWER-v = 0 → often maximum
height or stopping point.
Motion described as free fall - CORRECT ANSWER-Only force is weight →
acceleration = g.
Upward motion under gravity - CORRECT ANSWER-Choose sign convention
carefully → a = −g.
Maximum height reached - CORRECT ANSWER-Set v = 0 → find time or
displacement.
Time to hit the ground - CORRECT ANSWER-Use vertical SUVAT → ensure correct
displacement sign.
, Velocity-time graph given - CORRECT ANSWER-Gradient = acceleration → area =
displacement.
Area under v-t graph required - CORRECT ANSWER-Calculate geometric area →
include sign.
Acceleration-time graph given - CORRECT ANSWER-Integrate or find change in
velocity.
Force acts on a particle - CORRECT ANSWER-Draw free body diagram → identify
forces → apply F = ma.
Particle on rough horizontal surface - CORRECT ANSWER-Include friction opposing
motion → F = μR.
Particle on smooth surface - CORRECT ANSWER-No friction → simplify force
equation.
Object moving on an inclined plane - CORRECT ANSWER-Resolve forces parallel
and perpendicular to slope.
Force down slope required - CORRECT ANSWER-Use mg sinθ.
