Question

Write about acceleration and s.i unit also

Answer 1

$\huge\bold{Acceleration}$

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

Explanation:

acceleration can be defined as the rate at which the velocity changes or in other words change in velocity with respect to time.

acceleration=velocity(v)

time (t)

a=v-u

t

where u is initial velocity and v is final velocity and t is time

SI UNIT:m/s^2

the grahical representation of acceleration is represented by velocity-time graph where yaxis=velocity

xaxis=time

• When change in velocity is a decrease it can be noted as negative acceleration. or deceleration
