<span>Velocity, you divide distance/time </span>
Its tangential speed is constant although its velocity is changing. As the object changes direction, it results in a changing of positive and negative signs of the velocity. Although, the magnitude of the velocity (speed) is not changing.
Yes, for balance.hope this helped.
All the planets revolve around the sun counter clockwise and rotate on hteir axis counterclockwise except venus and neptune.
