Notes: If the earth stops rotating, then the impact of weight of a body will
be minimum on the Poles
. The maximum weight will be a t equator. … Thus the force due to gravity is not minimised at all and this in turn increases an object’s weight at the equator.
Would we gain weight if the Earth stopped spinning?
If the earth were not spinning,
you would be heavier as you would feel the full force of gravity
. Since there is more centrifugal force at the equator to cancel gravity, your overall weight at the equator versus at the poles is even less. … The centrifugal force at the poles is zero.
How does rotation of Earth affect weight?
Due to the rotation of the Earth about an axis, the weight of an object as well as the
gravitational acceleration differs at the poles as compared to the equator
. … Therefore, the person will weigh less at the equators than they will at the poles.
What would happen if the Earth’s rotation stopped?
At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped,
the momentum would send things flying eastward
. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
What will happen to the weight of the body at the South Pole if the Earth stops rotating?
As weight of body on pole = mg and
g does not change at the pole
due to rotation of earth, so there is no change in the weight of body.
Would gravity stop if the Earth stopped spinning?
The Earth is currently rotating on its axis, completing one turn approximately every 24 hours. This rotational velocity causes the Earth to bulge out around its equator, turning our planet into an oblate spheroid (a flattened ball). Without this spin,
gravity would be able to pull the Earth
into a nice perfect sphere.
Why don’t we feel the Earth spinning?
Earth moves very fast
. It spins (rotates) at a speed of about 1,000 miles (1600 kilometers) per hour and orbits around the Sun at a speed of about 67,000 miles (107,000 kilometers) per hour. We do not feel any of this motion because these speeds are constant.
What is the effect of shape of Earth on value of G?
Variation of g due to Shape of Earth
As the earth is an oblate spheroid,
its radius near the equator is more than its radius near poles
. Since for a source mass, the acceleration due to gravity is inversely proportional to the square of the radius of the earth, it varies with latitude due to the shape of the earth.
What is the rotating speed of Earth?
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly
1,000 miles per hour
.
Does rotation of 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. … The farther you are from the Earth’s axis the more centrifugal force you’ll experience.
How long can Earth last?
Gamma-ray burst or not, in
about a billion years
, most life on Earth will eventually die anyway due to a lack of oxygen. That’s according to a different study published in March in the journal Nature Geoscience. The researchers suggest that our oxygen-rich atmosphere is not a permanent feature of the planet.
Would the Earth stop spinning?
As scientists have established, the Earth is not going to stop spinning in our lifetimes, or for billions of years. … Basically, the Earth suddenly
stopping its rotation would completely destroy everything on the Earth’s surface
.
What happens if the moon gets destroyed?
Destroying the Moon would
send debris to Earth
, but it might not be life-exterminating. … If the blast were weak enough, the debris would re-form into one or more new moons; if it were too strong, there would be nothing left; of just the right magnitude, and it would create a ringed system around Earth.
What happens to the weight of the body if the weight becomes 1 16?
The height at which the weight of a body becomes[dfrac{1}{16}th], its weight on the surface of the earth (radius R), is
3R
. So, the correct answer is “Option A”.
What is the value of G at the Centre of the earth?
The value of g at the centre of the earth is
zero
.
What is the relation between the weight of an object on the earth and moon?
The moon’s gravitation force is
determined by the mass and the size of the moon
. Hence, the weight of an object on the moon is 1/6th its weight on the earth. The moon is far less massive than the Earth and has a different radius(R) as well.
