The physics
Acceleration is the rate of change of velocity — how many metres per second of speed an object gains (or loses) each second. A car doing 0–100 km/h in 6 seconds averages about 4.6 m/s², roughly half a g.
A sprinter reaching 10 m/s from 0 in 2 s
Answer: acceleration = 5 m/s² (in g-force 0.51 g).
What we know
- Initial velocity: 0 m/s
- Final velocity: 10 m/s
- Time: 2 s
Step by step
- Given
- v₀ = 0 m/s, v₁ = 10 m/s, t = 2 s
- Formula
- a = (v₁ − v₀) / t
- Substitute
- a = (10 − 0) / 2
- Result
- a = 5 m/s²
All results
| Acceleration | 5 m/s² |
|---|---|
| In g-force | 0.51 g |
