can someone help me with this problem:
"show that a point is traveling along the surface of a sphere if and only if its velocity vector is orthogonal to its position vector."
I know that it is true intuitively - since in centripetal motion, the velocity is always directed toward the center. but how do you prove this using vector calculus?
