Acceleration — a vector quantity that measures the rate of change of velocity with respect to time.

- Definition/formula: average acceleration a = Δv / Δt; instantaneous acceleration a = dv/dt.
- SI unit: metres per second squared (m/s²).
- Direction: same as the change in velocity (not necessarily the direction of motion). Example: speeding up, slowing down, or changing direction (centripetal acceleration).
