Why is acceleration due to gravity more at poles?
It is frequently stated that the value of the acceleration due to gravity at the pole is larger than at the equator because the poles are closer to the center of the earth due to the earth’s oblateness. The measured value is larger because the earth’s density is not uniform but increases toward the center.
Is the value of acceleration due to gravity is least on poles?
Answer. The value of acceleration due to gravity is least at the equator of the earth. Equatorial radius of earth is maximum while that at poles is minimum. Latitude at equator is zero as compared to 90° at the poles.
What is acceleration due to gravity where the value of g is maximum and minimum on the surface of Earth and why?
Find the difference in the maximum and minimum value of g on the surface of the earth. Thus, acceleration due to gravity is maximum at poles. Thus, acceleration due to gravity is minimum at the equator. A rocket is fired vertically with a speed of 5 km/s from the earth’s surface.
Why acceleration due to gravity is zero at Centre of Earth?
The acceleration due to gravity is the measure of gravitational attraction that Earth exerts on a body. So, when the body is at the center there is no need to pull it towards the center anymore. So, acceleration due to gravity is zero at the center of the Earth.
Which condition will acceleration due to gravity of Parachute be zero?
In a falling parachute, when a weight of the parachute becomes equal to the air resistance, its acceleration is zero.
At what height the acceleration due to gravity is 0?
Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m. s−2 per 3,200 km.)
Where the gravity is maximum?
The value of G is maximum at the poles. This is due to the closeness between the poles and the center of the earth. Stay tuned with BYJU’S to learn more about other concepts such as the acceleration due to gravity.
