Question

Define acceleration. Give it's S.I. unit.​

Answer 1

Answer:

change in velocity is called acceleration.

S.I. unit is m/s^2

hope it helps you dear☺️☺️☺️

Answer 2

Answer:

Acceleration : It means the rate of change of velocity of an object in an intervals of time is called as a acceleration.

There are 3 types of acceleration

1.positive acceleration

2.negative acceleration

3.zero acceleration

1) positive acceleration: it means the the final velocity (v), is greater than intial velocity (u) is called as positive acceleration

2. negative acceleration:it means the finalvelocity (v) is lesser than intial velocity (u)is called as a negative acceleration.

3) Zero acceleration: it means the velocity is zero is called as a zero acceleration

$accelaration = \frac{rate \: of \: change \: of \: velocity}{intervels \: of \: time \: } \: \: \: = a = \: \frac{v - u}{t} \:$

it si unit is m/sec²
