Question

Define acceleration. ​

Answer 1

Answer:

$the \: rate \: of \: change \: of \: velocity \: \\ is \: called \: acceleration$

$a = \frac{final \: velocity \: - initial \: velovty \: }{time}$

$its \: unit \: is \: \frac{m}{ {s}^{2} }$

Acceleration

• Defination ;-It is defined as the rate of change of velocity with respect to time
• Units ;- m/${s}^{2}$
• Dimensional Formula ;-$[{M}^{0}{L}^{1}{T}^{-2}]$

$\fbox{Types\:Of\:Acceleration}$

1. Uniform Acceleration :- If there is equal change in velocity in equal interval of time throughout the path
2. Non Uniform Acceleration:- If there is unequal change in velocity in equal interval of time or vice versa

Equations To Find The Uniform Acceleration:-

$1. \: v = u + at \\2. \: s = ut + \frac{1}{2} at {}^{2} \\ 3. \: {v}^{2} - {u}^{2} = 2as$
