Tides and centrifugal force

The Earth's center describes a circular orbit of radius c around the CM with angular velocity ω. Thinking about the points of the Earth's surface, we have to avoid a common misunderstanding. Saying that the Earth's center rotates around the CM, does not imply that the Earth as a whole is rotating around that point!

Continental Drift Theory

The polar-fleeing force relates to the rotation of the earth. Earth is not a perfect sphere; it has a bulge at the equator. This bulge is due to the rotation of the earth (greater centrifugal force at the equator). …

Do We Experience a Centrifugal Force from Earth's

A centrifugal force due to the Earth's rotation does appear in a frame fixed with respect to the rotating Earth (this is our everyday perspective of things here on the surface of the Earth). Similarly, a centrifugal force appears in a frame rotating with the Earth's orbit about the Sun. In such a frame the Earth and the Sun are standing still.

Question: Standard gravity for Earth is 9.80665 m/s2 and 32.1737 ft/s (based on 1m=3.2808 ft). These values take into account the centrifugal acceleration due to earth's rotation, which acts in the opposite direction of gravity due to Earth's mass. The Earth's diameter is 7,926 miles..

Gravity and centrifugal force

The centrifugal force does have an effect on the weight of objects on the Earth. It is about half the reason things are lighter at the equator than the poles, the other being that they are further from the center of the Earth, owing to its oblate shape (itself a result of the centrifugal force).

Why Don't Rockets Use Centrifugal Force for Launch?

2. How does centrifugal force affect rockets? Centrifugal force plays a crucial role in the operation of rockets. The force generated by the rotating motion of the rocket's engines creates a centrifugal force that enables the rocket to overcome the force of gravity and launch into space. 3. How does centrifugal force differ from centripetal …

In the Earth's frame of reference, there is no centrifugal force pulling the mass away from the centre of rotation, yet there is a very real force stretching the string attaching the mass to the nail. Using concepts related to centripetal force and Newton's third law, explain what force stretches the string, identifying its physical origin.

Centrifugal force

This centrifugal force is greater at the equator than at the pole because the material at the equator is further from the axis of rotation. Hence, the planet bulges at the equator. The Earth's surface is an equipotential, that is, no work is done moving upon the Earth's surface, either against gravity or against centrifugal force.
