Acceleration Calculator

Science & Engineering

Solve a, v, u, t, s with kinematic equations

Quick Answer

Acceleration Calculator: Solve a, v, u, t, s with kinematic equations. v = u + at.

Initial u (m/s)

Final v (m/s)

Time t (s)

Acceleration

3.473 m/s²

≈ 0.35 g

Distance111.12 m

g-force0.35 g

Δv27.78 m/s

Steps

1a = (v − u) ÷ t = (27.78 − 0) ÷ 8 = 3.473 m/s²
2s = ut + ½at² = 111.12 m

Acceleration benchmarks

Scenario	a (m/s²)	g
Elevator	1	0.10
Family car 0-100	3.5	0.36
Supercar 0-100	9.3	0.95
F1 car	15	1.53
Emergency brake	-8	-0.82
Free fall g	9.8	1.00

💡 Uniform acceleration: v = u + at, s = ut + ½at². Humans feel acceleration as g-force: sustained 5g causes blackout, which is why F1 drivers (4-6g in corners) train neck muscles. Negative a = deceleration (braking).

Formula & How It Works

Kinematic equations (constant acceleration)

v = u + at

s = ut + ½at² = (u+v)t/2

v² = u² + 2as

Five quantities (u, v, a, t, s) — know any three, solve the rest

Example: 0→100 km/h (27.8 m/s) in 6 s → a ≈ 4.63 m/s², s ≈ 83.3 m.
