How fast would the Earth have to spin for the centrifugal force to overpower gravity?
Force of gravity = Mass (m) x acceleration due to gravity (g)
Force of gravity = mg Centrifugal Force = Mass (m) x Radius of Earth(r) x Angular Velocity2 (̉ۡ2)
Centrifugal Force = mr̉ۡ2 The acceleration due to gravity (g) = 9.80665 m/s2.
Radius of Earth = 63,78,100 m Lets consider an equilibrium where both the above forces are equal. * mg = mrÉ2 * g = rÉ2 * rÉ2 = g We have to find a value of É that satisfies the above equation * rÉ2 = g * 63,78,100 x É2 = 9.80665 * É2 = 9.80665 / 63,78,100 * É2 = 1.53753469 × 10-6 * É = 1.23997367 x 10-3 At this angular velocity, the centrifugal force is exactly equal to the gravitational force. If the earth spins any faster than this, the Centrifugal force will overpower the gravitational force. The current angular velocity of Earth is 7.2921150 × 10−5 radians per second.
The ratio of the required angular velocity to the current angular velocity is 17.0043077.

Why don't astronauts walk very much in the space station?
There is no net gravity to keep their feet on the ground. In fact the gravity is cancelled out by the centrifugal force of the circular orbit,
What items do astronauts use to control gravity?
They dont. Gravity cannot be controlled. In sci-fi, sometimes rotation is used to simulate gravity via centrifugal force, but this has never been done.
How is a body still while the earth rotates?
It is due to gravity AND the earth turns slowly. The gravity has a force which makes you look like standing straight and if you're a Vietnamese, you'll be standing sideways because the "force" of gravity is doing its job.
What is the name of the force that makes the earth orbit the sun that starts with C?
The name of the force that makes the earth orbit the sun doesn't start with ' C '. The force that does it is the force of gravity.
What are forces that keep the moon in orbit around the earth?
Gravity keeps planets in orbit as it spins it creates gravity and gravitational pull keeps the a lined
Can you equate gravity and centrifugal force of earth?
Gravity is the force that pulls objects towards the center of the Earth, while centrifugal force is the outward force acting on an object moving in a circular path. On the surface of the Earth, gravity is much stronger than centrifugal force, which is why objects remain grounded. At the equator, where the centrifugal force is strongest due to the Earth's rotation, it partially counteracts gravity making objects slightly lighter.
Why is the force of gravity is not exactly the same everywhere on earths surface?
Two reasons: 1. Different distances from the Earth's center; 2. A "centrifugal force" that counteracts gravity in part.Two reasons: 1. Different distances from the Earth's center; 2.

Is Gravity is example of a centrifugal force?
No, gravity is not an example of a centrifugal force. Gravity is the force of attraction between objects with mass, while centrifugal force is the outward force experienced in a rotating reference frame.
What is G in centrifugal force 2000 G?
In the context of centrifugal force, "G" is a unit of measurement representing the force of gravity. When something experiences centrifugal force of 2000 G, it means the force applied to it is 2000 times that of Earth's gravitational force.
Will the moon fall down if there is no gravity?
No, it will be "catapulted" away from Earth because of the centrifugal force.
How the force responsible for the moon revolves around the earth?
The moon revolves around the earth - due to a balance between gravity and centrifugal force.
Would the earth stop orbiting the sun if there was no gravity?
Yes. Because of the centrifugal force, the Earth will be "catapulted" away from the sun. But don't worry, there is no way that gravity disappears!
How is the moon held in place orbiting the earth?
A balance between gravity and centrifugal force ! The gravity of the earth is always trying to pull the moon closer. However - as with any spinning object, centrifugal force is trying to 'fling' it out into space. The two forces cancel each other out, and thus the moon stays in orbit.
Why does water dont spill when earth revolves?
Water stays put on the Earth's surface as the force of gravity pulls it towards the center of the planet. The rotation of the Earth creates a centrifugal force that counteracts the gravity, resulting in a balance where water doesn't spill as the Earth rotates.
Does centrifugal force affect us since the earth is spinning so fast and does it influence the earths gravitational pull on us to some degree if so how much?
A "Centrifugal" force is a fake force. For example, if a person were to be spun in a circle, that person would feel like there was a force pulling them away from the center. However, that is not the case. The mass of the person has inertia and tries to escape the circle in a direction tangent to the circle at the point they are at.
Why earth is not spherical in shape and why it bulges at equator?
Earth is an oblate spheroid due to its rotation causing a centrifugal force that pushes material outward at the equator. This bulging at the equator is a result of the Earth's rotation, the centrifugal force causes the equatorial region to push outward, counteracting gravity and giving the Earth a slightly flattened shape.
The type of force that keeps objects moving in a circle or arc?
The type of force that keeps an object such as the Earth moving in a circle is a combination of gravity and centrifugal force. Gravity wants to pull the object inward, but centrifugal force wants to push the object outward. This combination keeps objects going in a circular path. You could also say that, for objects such as a rock attached to a rope that is swung in circles, the forces are the tension of the rope opposing centrifugal force. This is essentially the same thing, except with different forces at work.
