Question

what is acceleration????​

Answer 1

Acceleration

Acceleration is defined as the rate of change in velocity with respect to time. It is measured as metre per second square. In Mathematically,

$\implies \bar{a} = \dfrac{v - v_0}{\Delta t}$

$\implies \boxed{\bar{a} = \dfrac{\Delta v}{\Delta t}}$

Where, ā denotes acceleration, Δv denotes change in velocity and Δt denotes time taken or time intervals.

The unit of acceleration is metre per second square (m/s² or ms⁻²). And the dimensions of acceleration is [M⁰L¹T⁻²].

$\implies \bar{a} = \dfrac{\Delta v}{\Delta t}$

$\implies \bar{a} = \dfrac{[M^0L^1T^{-1}]}{[M^0L^0T^{1}]}$

$\implies \boxed{\bar{a} = [M^0L^1T^{-2}]}$

Answer 2

$⍟ \: \underline{ \pink{ \rm Acceleration\: : }}$

The Rate of change in Velocity with respect to its Time.

let,

u - initial velocity

v - final velocity

t - time

so, it is formuka given by :

$\boxed{ \orange{ \large{ \rm a = \frac{v - u}{t} }}}$

or,

$\boxed{ \large{ \color{green} \rm a = \frac{ \triangle v}{ \triangle t} }}$

where,

∆v → Change in Velocity

∆t → Change in Time
