Question

Diomention of acceleration

Answer 1

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

Dimension: L T −2

Answer 2

Answer:

Dimensional Formula of Acceleration

The dimensional formula of acceleration is given by,

M0 L1 T-2

Where,

M = Mass

L = Length

T = Time

Derivation

Acceleration (a) = Velocity × Time-1 . . . . . (1)

Since, Velocity (V) = Displacement × Time-1

∴ The dimensional formula of velocity is [M0 L1 T-1] . . . . (2)

On substituting equation (2) in equation (1) we get,

Acceleration = Velocity × Time-1

Or, a = [M0 L1 T-1] × [T] = [M0 L1 T-2]

Therefore, acceleration is dimensionally represented as [M0 L1 T-2].
