Question

what is the acceleration

Answer 1

$Here \: is \: the \: answer \: of \: your \: question$


`$\textbf{Acceleration}$`

→ It is the rate of change of velocity of an object with respect to time. i.e.

Acceleration = Velocity ÷ Time


`$\textbf{Dimension}$`

→ Acceleration = Velocity ÷ Time ........(1)

Here, the dimension of

Velocity = [L¹T-¹]

Time = [T¹]

Now, put dimensions of velocity and time in (1)

Acceleration = [L¹T-¹] ÷ [T¹]

Acceleration = [L¹T-²]



`$\textbf{Other impotant points}$`

→ Unit of velocity = metre/ second

and time = second

So,

S.I unit of acceleration = m/s²

→ It is a vector quantity. As it has both magnitude and direction.

Answer 2

Here's your answer!!

__________________________

•Change in velocity with respect to time is called Acceleration.

$acceleration = \frac{change \: in \: velocity}{time}$
