What Is The Speed Of Gravity? 

You might have learned about gravity during your schooling to lets go through speed of gravity in detail. And also how to calculate the rate of gravity by using a formula. Gravity is the natural force that attracts things toward it. When you fall something, it automatically falls on the ground instead of going upward. Why does this happen? This happened because of the gravitational force present on the Earth. And the force of gravity keeps all planets in orbit around the sun. Gravity operates on objects of all sizes, from subatomic particles to clusters of galaxies. Without further delay let’s know the speed of gravity.      

What Is The Speed Of Gravity? 

The speed of gravity is equal to the speed of light, according to Einstein’s General Relativity. However, Kipeikin and Fomalon came to the conclusion that the speed of gravity is between 0.8 and 1.2 the speed of light, which fully agrees with the theoretical prediction of general relativity that the speed of gravity is exactly the same as the speed of light.

Calculating the Earth’s gravitational velocity in feet per second is practically impossible, so we need to calculate the acceleration first. And from acceleration, you can calculate what is the maximum speed of gravity.   

Here are the different speeds of gravity, 

  • The speed of gravity m/s is approximately 9.81 m/s2 
  • The speed of gravity in meters per second is 9.8 meters per second squared 
  • The speed of gravity mph is 21.937 miles per hour 
  • The speed of gravity in feet per second is 32.17 feet per second square  
  • The maximum speed of gravity is 299,792,458 meters per second  

Calculate The Speed Of Gravity 

To calculate the speed of gravity on Earth, we need to account for falling objects. The Earth’s gravitational rate cannot be calculated directly without a reference object. Because gravity is a force, not linear motion. So you can calculate acceleration and you can calculate velocity from acceleration. 

So, the acceleration due to gravity on the surface of the earth is, 

g = GMm(R+H)2  but, at the surface H = 1 

Therefore, g = GMmR2  

Here, G = Gravitational constant and its value is 6.6734 X 10-11 m3kg-1s-2

          Mm is the total mass enclosed within radius R 

As you know, Earth’s gravity is not constant and varies with altitude. You can find the gravitational force at any height using the gravitational ratio formula, 

gh = g0(ReRe + h)2


             gh is the gravitational acceleration at height h 

             Re is the Earth’s mean radius.

             g0 is the standard gravitational acceleration.

About Gravity

Gravity, expressed in g, is the net acceleration imparted to an object due to the combined action of gravity and centrifugal force. The Earth rotates in a circle and has an angular velocity. That is, the Earth’s gravitational angular velocity is g = 10 m/s2, R = 6400 km, which equals 15.04108°/mean solar hour. Like the Earth, the Moon has gravity, and the Moon’s gravity is 1.62 m/s 2. 

. According to Einstein’s general theory of relativity, Earth’s gravity moves at the speed of light.

If you look at the Earth’s gravitational limit in kilometers, you can see that the exact strength of Earth’s gravity varies from location to location.

Is Gravity 9.8 Meters Per Second?

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.

Does The Force Of Gravity Have A Speed?

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!

How Fast Is Gravity Vs Light?

Kopeikin and Fomalont concluded that the speed of gravity is between 0.8 and 1.2 times the speed of light, which would be fully consistent with the theoretical prediction of general relativity that the speed of gravity is exactly the same as the speed of light.

Why Is Gravity The Same Speed As Light?

Creighton explains that in electromagnetism, when you shake an electron, it creates a change in the electric field that spreads out at the speed of light. Gravity works the same way. Shake a mass and the change in the gravitational field — the gravitational wave — propagates at that same speed.

Is Gravity 9.8 Or 10?

You should assume g value as 9.8 m/s2 unless mentioned in the question as 10 m/s2. Q. What is the value of acceleration due to gravity on the moon?


Gravity is very important to us even though we can not live on the Earth without gravitational force. The gravity of the Sun keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the Sun’s light and warmth. It has down our atmosphere and the air we need to breathe. You walk on the ground very easily, it is because of the gravitational force. If there was no gravity, then you would float away instead of walking on the ground. Also, gravity causes a piece of paper that is blowing in the wind to come down to Earth ultimately with the speed of gravity.
