Question

What is acceleration ? Explain its
formula ands SI unit in brief​

Answer 1

Answer:

Explanation:

Acceleration has the dimensions of velocity (L/T) divided by time, i.e. L T−2. The SI unit of acceleration is the metre per second squared (m s−2); or "metre per second per second", as the velocity in metres per second changes by the acceleration value, every second. SI unit: m/s2, m·s−2, m s−2.

Answer 2

Acceleration :-

• Acceleration is defined as change in velocity per unit time .

S.I. unit :-

• m/s²

Formulae :-

• a = v - u/t
• a = ∆v/t

Where ,

• a → acceleration
• v → final velocity
• u → initial velocity
• t → time taken to change velocity

Dimensional formula :-

Deriving the dimensional formula using S.I. unit.

• m/s²

Where ,

• m → L
• s-² → T-²

• Dimensional formula :- [ LT-² ]
