Question

Write about acceleration..................♥️

Answer 1

$\huge\mathfrak{Acceleration}$

It is the rate of change of velocity.

a = (v - u )/t

Where,

a is Acceleration

v is final velocity

u is initial velocity

and t is time taken.

_____________________

Types :

there are three types if acceleration :

Positive acceleration

negative acceleration ( or retardation )

zero acceleration

____________________

S.I unit ----> m/s²

Answer 2

Acceleration :

The rate of change of velocity of an object with respect to time is known as acceleration.

i.e.

Acceleration = $\dfrac{Change\:in\: velocity}{Time\:taken}$

• Velocity is measured in m/s

• Time measured in s (sec)

So,

S.I. unit of acceleration = m/s²

Types of acceleration :

» Positive acceleration

» Negative acceleration

» Zero acceleration

Dimension :

• Dimension for velocity is LT-¹

• Dimension for time is T

So,

Dimension of acceleration is LT-²
