Question

what is acceleration and what is the si unit??​

Answer 1

Answer:

A = V/T , SI Unit = m/s^2

Explanation:

Acceleration is defined as velocity of the body by time taken.

A = V/T

Its SI Unit is m/s^2

Velocity SI Unit = m/s

=> A = m/s*s = m/s^2

Answer 2

$\large\underline\mathrm\red{Acceleration \: :-}$

The rate of change of velocity is said to be ‘acceleration’. It's SI unit is m/s² or cm/s².

• Acceleration is a vector quantity.
• For acceleration, There should be change in speed and direction.
• If the speed and direction is not changing, then it can be said that the object is not accelerating.

FORMULA :

• Acceleration = $\sf \dfrac {Final \: velocity - Initial \: velocity}{time} \rightarrow \dfrac {\Delta v_f - \Delta v_i}{t}$

ADDITIONAL INFORMATION :

• Acceleration will be zero, if a body moves with uniform velocity.
• A body is said to be in uniform motion if it is moving on a straight line.
• If a body is moving on a straight line then the velocity will increase by a equal amount in equal intervals of time.
