Acceleration Calculator
Going from 5 m/s to 25 m/s in 10 seconds is an acceleration of 2 m/s², from a = (v − u)/t.
2 m/s²
- In ft/s²
- 6.56167979 ft/s²
- In g
- 0.2039432426 g
- Distance covered (u + v)t/2
- 150 m
Step-by-step solution
- a = (v − u) ÷ t
- a = (25 − 5) ÷ 10
- a = 2 m/s²
Acceleration Formula
a = (v − u) / t
a acceleration, v final velocity, u initial velocity, t time taken
Worked Example
A car that speeds up from 5 m/s to 25 m/s in 10 s:
- a = (v − u) ÷ t
- a = (25 − 5) ÷ 10
- a = 2 m/s²
In g: 0.2039432426 g · Distance covered (u + v)t/2: 150 m
Acceleration in g
Dividing by standard gravity 9.80665 m/s² gives acceleration in g. Choose g as the answer unit: a family car manages about 0.3 g, a roller coaster up to 4–5 g.

Projectile Motion Calculator
R = v₀ cos θ × T, H = h₀ + (v₀ sin θ)²/2g
T = (v₀ sin θ + √((v₀ sin θ)² + 2gh₀))/g; on level ground R = v₀² sin 2θ / g
Example: A ball kicked at 20 m/s and 45° from ground level (g = 9.80665 m/s²): Range R = 40.7886 m.
Frequently asked questions
What does negative acceleration mean?
The velocity is decreasing in the chosen positive direction (deceleration). Braking from 25 m/s to 5 m/s in 10 s is a = −2 m/s².
How do I convert 0–100 km/h times to acceleration?
Change 100 km/h to 27.78 m/s and divide by the time: 0–100 km/h in 8 s is about 3.47 m/s², or 0.35 g.
