How it's calculated
a = (v − v₀) ÷ t
a = acceleration, v = final velocity, v₀ = initial velocity, t = time. Other modes: a = F ÷ m (Newton's 2nd law), a = g (free-fall gravity), or a = 26.8224 ÷ t₀₋₆₀ from a 0–60 mph time.
Common questions
What is the formula for acceleration from force?
Newton's second law gives a = F / m, force divided by mass.
What is free-fall acceleration on Earth?
About 9.81 m/s squared, often written as 1 g. The Moon is roughly 1.62 and Mars about 3.72.
