Acceleration

calculate

Try it yourself

calculate: work out the answer from the data.

A cyclist speeds up steadily from 2.0 m/s to 8.0 m/s in 4.0 s. Calculate her acceleration.

Give your answer with its unit

Type numbers like 0.25 or 2.5x10^-3. Put the unit in its own box, for example g, cm3 or m/s. Leave the unit box empty if the quantity has no unit.

Cambridge IGCSE Physics 0625 · 2026–2028 v2 · Original learning materials.

The acceleration of free fall g, approximately constant near the Earth and about 9.8 m/s² (1.2.8); acceleration as the change in velocity per unit time, a = Δv ÷ Δt (1.2.9); constant and changing acceleration from data and from a speed–time graph (1.2.10); acceleration from the gradient of a speed–time graph (1.2.11); deceleration as a negative acceleration (1.2.12); falling in a uniform gravitational field with and without air or liquid resistance, and terminal velocity (1.2.13); friction between solid surfaces, which impedes motion and causes heating (1.5.1.6); drag in liquids and air resistance in gases (1.5.1.7, 1.5.1.8). Resultant force, F = ma and Newton’s first law are in FORCE01.

Apparatus, amounts and times in the experiment are illustrative. Real practical work follows a teacher-approved safety method.
