Question

what is acceleration​

Answer 1

$\huge\underline\pink{\dag{\sf{ ANSWER}}\dag}$

$\bold\purple{Acceleration}$is the rate of change of the velocity of an object with respect to time.

The first formula of acceleration is from Newton’s second law relates force, mass, and acceleration in an equation. Thus, the formula is: $\fbox{F= ma}$

Answer 2

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
