If the Earth spun faster or slower would it affect gravity?

Question

I always thought it depended on the mass of the object, but a friend disagrees......

Answer 1

no. gravity is a function of mass. thats it.

also, there is no such thing as "centrifugal force." there is "centripetal acceleration", however. ask your science/physics teacher.

Answer 2

Mass is a big part of the equassion but your distance from the center of gravity is also the issue if you are being swung around it as we are on the earth. Satellite orbits are determined by this principle. Even though you are standing on the surface of the earth you are being swung around the center at a certain speed. If that speed increased you would be swung faster away from the center and depending on the increase of speed you indeed would become less heavy although all objects including scales used to determine the difference would also be effected. Try swing a bucket of water over your head swiftly then slowly. See what happens.

Answer 3

It would not affect gravity immediately, because gravity is only dependent on mass and distance [you are not changing either the mass of the earth, your mass, or the distance between you and the center of the Earth.]

BUT

Over time, if the earth were spinning very quickly, the shape of the Earth would slowly change. The equator would bulge more and the poles would retract a bit.

So, if the Earth went faster, and you waited long enough for the earth to change shape, you would weigh less at the equator and more at the poles.

Answer 4

It will not effect gravity. It will reduce the centripital or center seeking force. You will then have a smaller apparent weight if the earth speeds up, a larger on if the earth speeds down. The actual amount of force is VERY small though. If the earth stopped you would be almost exactly the same weight if you ignore the earthquakes and tidal waves.

Answer 5

Planets are initially formed via bits of 'dirt' that clump mutually by way of gravity. those clumps would have an extremely small spin by way of incontrovertible fact that the are no longer incredibly comparable. As gravity packs the clump right into a smaller quantity the spin will advance. As there's no friction in area, the Earth's continues to be spinning at present, billions of years after it has formed and commenced spinning. There are 2 diverse strategies of measuring the fee of the Earth's spin, making use of angular speed and linear speed. It takes the Earth type of 24 hours to spin 360 levels, as a result it has an angular speed of approximately 15 levels according to hour (or 0.004 levels according to 2d). Linear speed is adjustments counting on the place you're on the earth, although. on the poles the linear speed is 0, while it as a optimal on the equator by way of fact the Earth has to holiday added the flow around 360 levels there. on the equator the linear speed is type of one thousand mph. some thrilling factors: -The spin of the Earth is unquestionably slowing down by way of fact the tides of the Moon create friction, meaning days will slowly become longer and longer. -by way of conservation of angular momentum, each time you spin around you impression the angular speed of the Earth. Spin anti-clockwise to decelerate the Earth and clockwise to hurry it up. of course the top result's negligible by way of Earth's extensive mass. -A nautical mile is according to how some distance the Earth spins in a single minute on the equator.

Answer 6

It would not actually affect the force due to gravity. However, it would affect the "centrifugal force," which pulls you away from the earth's axis. The number you read when you step on the scale, is a combination of gravitational force and centrifugal force.
