Does centripetal acceleration affect gravity?

Centripetal forces cause centripetal accelerations. In the special case of the Earth’s circular motion around the Sun – or any satellite’s circular motion around any celestial body – the centripetal force causing the motion is the result of the gravitational attraction between them.

Does the spinning of the Earth affect gravity?

While the spinning of the Earth doesn’t directly affect gravity, it does off-set it a little. At the north and south poles objects weigh exactly what they should, and at the equator things weigh slightly less.

Is Earth gravity centripetal force?

For the rotating Earth, centripetal force is supplied by the gravitational force towards Earth’s center.) If Earth was a perfect, rigid sphere, the ocean would be 20 km deeper at the equator than at the poles.

What is centripetal acceleration on Earth?

Earth’s period of rotation is a sidereal day (86164.1 seconds, slightly less than 24 hours), and the equatorial radius of the Earth is about 6378 km. This means that the centripetal acceleration at the Equator is about 0.03 m/s2 (metres per second squared).

How does centripetal force affect gravity?

A centripetal force directed towards the center of the turn is required for any object to move in a circular path. Thus, the “gravity” force felt by an object is the centrifugal force perceived in the rotating frame of reference as pointing “downwards” towards the hull.

Why is centripetal force equal to the force of gravity?

Bottom line, if a body is not accelerating (stopped or uniform velocity) the sum of ALL forces acting on it must be zero so that f = ma = 0. And that’s why centripetal force and weight are “equal” in your case.

Does centripetal force affect gravity?

Gravity along with all other fundamental forces (electromagnetic, strong and weak) have effects on the centripetal force and nothing else can affect it.

What creates the Earth’s gravity?

Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That’s what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.

Where on the earth’s surface is your centripetal acceleration greater at the equator or at the poles?

The person at the equator moves in a larger circle so that r is larger for the person at the equator. Therefore, the person at the equator has a larger centripetal acceleration than the person at the north pole.

What causes the Earth to have gravity?

Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn’t really have an effect on our planet.

Does centripetal acceleration affect the gravity of an object?

This force is formal and applied on a par with the gravitational force of Newton. No. gravity is an affect of mass. Centripetal acceleration will effect the weight of an object on the surface of the earth such that objects at the equator will weight slightly less then objects at the poles.

What is the acceleration due to gravity at the earth’s surface?

An object sitting stationary relative to the surface of the earth, however, is not in equilibrium. The acceleration due to gravity at the earth’s surface is about 9.8 m/s2, whereas the centripetal acceleration is only 0.033 m/s2. Highly active question.

How does centrifugal force affect the speed of an object falling?

The centrifugal force due to the rotation of the planet on it’s axis opposes the force of gravity – meaning that the actual rate that an object falls when released from some height is slightly slower than you’d predict from gravity alone.

Does the Earth’s rotation affect the weight of an object?

Yup, the earth’s rotation makes the weight of objects a little less at the equator. Gravity pulls down, but the object needs to accelerate in the downwards direction in order to stay in a circular path around the Earth’s rotational axis in order to stay on the Earth’s surface as it turns.
