Question

what is acceleration ??
difference between acceleration and velocity ​

Answer 1

The definition of Acceleration:

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

The formula used to find Acceleration:

$Acceleration = \frac{Final \;velocity - Initial \; velocity}{Time \; taken}$

The SI unit of Acceleration:

The unit of acceleration is metre per second square (m/s² or ms⁻²).

The dimensional formula for Acceleration:

$[M^{0}L^{1}T^{-2}]$

$\rule{300}{2}$

The definition of velocity:

Velocity is defined as the rate of change of displacement of an object in a particular direction.

The formula used to find Velocity:

$Velocity = \frac{Displacement}{Time\;taken}$

The SI unit of Velocity:

The SI unit of velocity is metre per second (m/s or ms⁻¹).

The dimensional formula for Velocity:

$[M^{0}L^{1}T^{-1}]$

Answer 2

Acceleration :

Definition : Acceleration is defined as the change in the velocity of an object with respect to time.

It is Denoted by a .

Formula :

$\rm Acceleration = \frac{final \: velocity - initial \: velocity}{time}$

$\rm⇢ \: \: a = \frac{v - u}{t}$

SI Unit : SI unit of Acceleration is m/s² .

$_________________________________$

Velocity :

Definition : Velocity is defined as the speed of an object in a particular direction.

It is Denoted by v .

Formula :

$\rm Velocity = \frac{Displacement }{Time \: \: taken }$

$\rm⇢ \: \: v = \frac{s}{t}$

SI Unit : SI unit of Velocity is m/s .
