Acceleration Calculator
Calculate acceleration from initial velocity, final velocity, and time. Plus distance traveled.
What is Acceleration Calculator?
The acceleration calculator applies a = (v − v₀) / t. Useful for vehicle 0–60 times, free fall, and any change-in-motion problem.
Formula
a = (v − v₀) / t. Distance: d = v₀ × t + ½ × a × t².
Worked example
Car going 0 to 30 m/s (~67 mph) in 10 seconds: a = 30/10 = 3 m/s² ≈ 0.31 g. Distance: 150 m.
How to use this calculator
- Enter initial and final velocities and time.
- Acceleration, g-force equivalent, and distance appear.
Frequently asked questions
What's a g-force?
g-force is acceleration relative to Earth's gravity (9.81 m/s²). 1g = standing still on Earth. 2g = roughly the launch of a sports car. 5g = top of a roller coaster loop. 9g+ = trained pilots only.
Acceleration vs deceleration?
Same physics, different sign. Deceleration is negative acceleration — velocity decreasing instead of increasing.
How does this relate to F = ma?
Once you have acceleration, multiplying by mass gives the force required: F = ma. A 1500 kg car at 3 m/s² needs 4500 N of net force from the engine (minus drag and friction).
Constant vs variable acceleration?
This calculator assumes constant acceleration. For variable acceleration (e.g., a car changing throttle), need calculus or instantaneous values.
