Use the formula: acceleration = change in velocity ÷ time
Write it as: a = (v – u) ÷ t
Identify the initial velocity
Identify the final velocity
Find the time taken
Subtract initial velocity from final velocity
Divide the result by the time taken
Use units of m/s²
If velocity is changing in a graph, find the slope of the velocity-time graph
If force and mass are given, use: a = F ÷ m
