SOLAR SYSTEM

Detailed explanation-1: -Tangential velocity vector is always parallel to the radius of the circular path along which the object moves. Tangential velocity vector is always perpendicular to the radius of the circular path along which the object moves.

Detailed explanation-2: -The tangential velocity is equal to the product of the angular velocity and the radius of the orbit.

Detailed explanation-3: -The velocity of the satellite would be directed tangent to the circle at every point along its path. The acceleration of the satellite would be directed towards the center of the circle-towards the central body that it is orbiting.

Detailed explanation-4: -The direction of the tangential acceleration vector is always parallel to the tangential velocity, and perpendicular to the radius vector of the circular motion.

Detailed explanation-5: -Angular velocity is the same for all points on Earth, while tangential velocity decreases from the equator to the poles. Tangential velocity is the same for all points on Earth, while angular velocity decreases from the equator to the poles.

Detailed explanation-6: -The sideways (what astronomers call tangential) velocity is about 30 kilometers (18 miles) per second, which is incredibly fast. But then, we do travel an orbit that’s nearly a billion kilometers in circumference every year!
