Question

what is acceleration​

Answer 1

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.

The SI unit of acceleration is the metre per second squared (m s−2); or "metre per second per second", as the velocity in metres per second changes by the acceleration value, every second.

Answer 2

Step-by-step explanation:

Answer:

Acceleration is a vector quantity that defines rate at which the object changes its speed with direction
