Question

what is acceleration??



._.​

Answer 1

$\large\star{\boxed{\mathfrak{\purple{ Answer \ :- }}}}$

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

Answer 2

Answer:

Acceleration is defined as

"The rate of change of velocity with respect to time"

Acceleration is a vector quantity as it has both magnitude and direction. It is also the second derivative of position with respect to time or it is the first derivative of velocity with respect to time.
