If Earth somehow expanded to a larger radius, with no change in mass, how would your weight be affected? How would it be affected if Earth instead shrunk? (Hint: Let the equation for gravitational force guide your thinking.)
Consider an airplane that flies due east on a trip, then turns flying due west. Flying in one direction, the plane flies with Earth’s rotation, and in the opposite direction, against Earth’s rotation. But, in the absence of winds, the times of flight are equal either way. Why is this so? What would happen if there were no absence of wind?
