Question

What is Acceleration ?? ​

Answer 1

Answer:

the velocity of the particle changes at a constant rate, then this rate is called the constant acceleration. ... For example, if the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 2 m/s to 5 m/s over one second, then its constant acceleration is 3 m/s2.

Step-by-step explanation:

SI unit is- metre per second

can i know why are u wasting points army ⟬⟭?

Answer 2

Step-by-step explanation:

Rate of change in velocity is called acceleration.

acceleration =velocity final-velocity initial/time

i.e

$a = vf - vi\t$
