Measurement Motion
Key knowledge — Measurement Motion
Formulas & equations
Speed = distance ÷ timeAcceleration = change in velocity ÷ time = (v − u) ÷ tv = u + ats = ut + ½at²v² = u² + 2ass = 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.
