For a moving body, at any instant of time

Choose an answer

If the body is not moving the acceleration is necessarily zero

If the body is slowing, the retardation is negative

If the body is slowing, the distance is negative

If displacement, velocity and acceleration at that instant are known, we can find the displacement at any given time in future
