Acceleration Calculator

Calculate acceleration as the rate of change of velocity over time. Positive = speeding up, negative = slowing down (deceleration).

a = (v₂ - v₁) / t

a = acceleration, v₂ = final velocity, v₁ = initial velocity, t = time. Earth's gravity: 9.8 m/s².

What is negative acceleration?

Negative acceleration (deceleration) means slowing down. The object's velocity is decreasing over time.

What is g-force?

1g = 9.8 m/s² (Earth's gravity). Roller coasters can reach 3-6g. Fighter pilots experience up to 9g.
