Question

difine acceleration please answer bhai log behen log sabhi bada ans. do bhai please fast​

Answer 1

                Acceleration

Acceleration, in physics is defined as the rate of change of velocity.

• $\bold{\mathff{Acceleration =\dfrac{Change\:in\: velocity}{Time}}}$

• It is a vector quantity and has magnitude as well as direction. The magnitude of acceleration can be positive negative and zero.

• The SI unit of acceleration is  $\bold{\mathff{\dfrac{m}{sec^2}}}$

• Its dimension = $\bold{\mathff{[LT^{-2}]}}$

               The quantity acceleration is an important term of in Physics. The product of mass and acceleration is Force. Therefore, force is directly proportional to the acceleration produced in the body. Evidently it specifies the motion of an object.

Answer 2

━━━━━━━━━━━━━━━━━━━━

Acceleration:-

• The rate of change of velocity is known as Acceleration.

• Acceleration is a vector quantity.

• The SI unit of acceleration is m/s^2.

Formula:-

a= v-u/t

a = acceleration

v= Final velocity

u=initial velocity

t= time

• Acceleration is a measure of how fast velocity changes.

• Acceleration is a vector, and therefore includes both a size and a direction.

Example:-

acceleration is increasing your driving speed from 45 to 55 to merge with traffic.
