What is the correct equation for finding the acceleration?
- Aa = (v − u)/t
- Ba = u + vt
- Ca = (v + u)/t
- Da = (v + u)/2
Show answer and explanation
Correct answer: (a) a = (v − u)/t
Explanation
Acceleration is the rate of change of velocity with time.
If velocity changes from initial u to final v in time t, then a = (v − u) / t.
It is a vector quantity with SI unit m s⁻².
