Is gravity stronger at the equator?
Gravity is often assumed to be the same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense. In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet’s rotation.
How much less is gravity at the equator?
The effective acceleration of gravity at the poles is 980.665 cm/sec/sec while at the equator it is 3.39 cm/sec/sec less due to the centrifugal force. If you weighed 100 pounds at the north pole on a spring scale, at the equator you would weigh 99.65 pounds, or 5.5 ounces less.
Where is the Earth gravity strongest?
Gravity is strongest at the Earth’s surface, and its weakest at the Earth’s core.
Where is the earth gravity strongest?
What is the gravity of the Earth at the equator?
The gravity of Earth at the equator is 9.789 m/s2, while the force of gravity at the poles is 9.832 m/s2.
What does gravity mean?
Gravity means probably weight (it is the force by which an earth attract every object towoards its centre). W = mg where m = mass of body and g = acceleration due to gravity . g depends inversely to square of the radius of earth . Since due to the geometry of the earth its has more radius in equator and less radius in poles .
Why is there a difference in gravity at different latitudes?
The second major reason for the difference in gravity at different latitudes is that the Earth’s equatorial bulge (itself also caused by centrifugal force from rotation) causes objects at the Equator to be farther from the planet’s centre than objects at the poles.
What is the variation in magnitude of gravity across the Earth?
Variation in magnitude. The Earth is rotating and is also not spherically symmetric; rather, it is slightly flatter at the poles while bulging at the Equator: an oblate spheroid. There are consequently slight deviations in the magnitude of gravity across its surface.
