## Where is gravity strongest on earth?

Arctic OceanMount 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..

## What is the force of gravity on the moon?

1.62 m/s²Moon/Gravity

## What is the three laws of gravity?

Newton’s Three Laws of Motion and his Law of Gravity are probably the most famous of all physics. … Newton’s Second Law of Motion says that force is equal to the mass of the object times its acceleration. Remember, a force is a push or pull, and mass just means how much of the object you have.

## How is gravity measured?

Gravity is measured by the acceleration that it gives to freely falling objects. At Earth’s surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second. Thus, for every second an object is in free fall, its speed increases by about 9.8 metres per second.

## How is 9.81 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.

## Why is gravity 9.81 ms 2?

A: Gravity (or the acceleration due to gravity) is 9.81 meters per second squared, on the surface of Earth, because of the size of Earth and the distance we are on its surface from its center. Throughout space, gravity actually is constant. …

## What are the 3 laws of gravity?

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

## How fast is gravity?

The best results, at the present time, tell us that the speed of gravity is between 2.993 × 10^8 and 3.003 × 10^8 meters per second, which is an amazing confirmation of General Relativity and a terrible difficulty for alternative theories of gravity that don’t reduce to General Relativity!

## What is the formula for gravity?

The formula is F = G*((m sub 1*m sub 2)/r^2), where F is the force of attraction between the two bodies, G is the universal gravitational constant, m sub 1 is the mass of the first object, m sub 2 is the mass of the second object and r is the distance between the centers of each object.

## What is the measurement of gravity on Earth?

9.807 m/s²Earth/Gravity

## At what height gravity is zero?

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.)
