Use the formula: acceleration = change in velocity ÷ time taken
Subtract initial velocity from final velocity to find change in velocity
Divide the change in velocity by the time interval
Write the result in units of m/s²
If mass and net force are known, use acceleration = net force ÷ mass
If velocity is changing over time on a graph, find the slope of the velocity-time graph
If position and time data are given, calculate velocity first, then determine acceleration from the change in velocity over time
