Question: what is the equation that describes acceleration?
Answer: Another formula, acceleration (a) equals change in velocity (Δv) divided by change in time (Δt), calculates the rate of change in velocity over time. This formula may be written a = Δv ÷ Δt. ... In science, the units for acceleration usually will be meters per second per second (m/s/s) or meters per second squared (m/s2).
