Gravity is the reason things with mass or energy are attracted to each other. The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you feel as gravity.
Is gravity caused by the Earth spinning?
Explanation: Gravity is caused by mass curving the fabric of spacetime. The Earth's gravity is due to the Earth's mass and nothing else. If the Earth wasn't spinning at all it would still have gravity.
Where is highest gravity on Earth?
Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s2, while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s2.
Where is gravity the weakest on earth?
the equator
Is gravity stronger at the center of the earth?
As you move towards the center, there is less and less of the Earth closer to the center than you are, so the gravitational field gets weaker and your weight decreases. At the exact center of the Earth, the gravitational field is actually zero.
Where is gravity strongest on earth poles or equator?
- The centrifugal force cancels out the gravity minimally, more so at the equator than at the poles.
- The poles are closer to the center due to the equatorial bulge, and thus have a stronger gravitational field.
When we say g 9.8 What does this mean?
The magnitude of the acceleration due to gravity, denoted with a lower case g, is 9.8 m/sm/sThe metre per second is an SI derived unit of both speed (scalar quantity) and velocity (vector quantity (which have direction and magnitude)), equal to the speed of a body covering a distance of one metre in a time of one second.https://en.wikipedia.org › wiki › Metre_per_secondMetre per second - Wikipedia2. g = 9.8 m/s2. This means that every second an object is in free fall, gravity will cause the velocity of the object to increase 9.8 m/s.Oct 4, 2021
Is gravity 9.8 meters per second?
As noted above, the acceleration due to gravity at the surface of Earth is about 9.8 metres per second per second.
How 9.81 is calculated?
The acceleration g=F/m1 due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s-2.
What is the value of g'on Earth?
9.8 m/s2
Does gravity vary on Earth?
The acceleration g varies by about 1/2 of 1 percent with position on Earth's surface, from about 9.78 metres per second per second at the Equator to approximately 9.83 metres per second per second at the poles.
