The earth bulges slightly at the equator, due to the centrifugal force in the earth??s rotating frame.
Question:
The earth bulges slightly at the equator, due to the centrifugal force in the earth??s rotating frame. Show that the height of a point on the earth (relative to a spherical earth), is given bywhere ? is the polar angle (the angle down from the north pole), and R is the radius of the earth.
(3 sin? 0-2). 6g (9.27)

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
