The acceleration of a body is the amount of change in the velocity of the body with time. It is a vector quantity, and hence the acceleration of a body can be positive, negative, or zero.

When it is positive, the body's velocity is increasing with time.

When it is negative, the body's velocity is decreasing with time.

When it is zero, the body's velocity is not changing with time.
