Cambridge IGCSE·Co-ordinated Sciences 0654·Physics Motion Graphs

📋Key knowledge — Measurement Motion

Formulas & equations

Speed = distance ÷ time
Acceleration = change in velocity ÷ time = (v − u) ÷ t
v = u + at
s = ut + ½at²
v² = u² + 2as
s = ½(u + v)t

Key facts & rules

Distance-time graph: gradient = speed. Horizontal line = stationary. Curved = acceleration.
Velocity-time graph: gradient = acceleration. Area under graph = distance travelled.
Scalar: magnitude only (speed, distance, mass, temperature, time).
Vector: magnitude AND direction (velocity, displacement, acceleration, force, momentum).
Free fall: acceleration due to gravity g ≈ 10 m/s² (or 9.8 m/s²).
Uniform acceleration: constant change in velocity per second.
