How easy was it to use our calculator? Did you face any problem, tell us!

The free online gravity calculator helps you to calculate gravitational force between two objects towards the earth. The calculator makes use of the most accurate International gravity equations to determine how much potential does exist among objects of certain masses for attraction.

Let’s move down to the article below that is packed with sound information of the force of gravity.

Let’s go!

What Is Gravity?

“The force with which the Earth attracts objects or bodies towards itself is called force of gravity”


Universal Law of Gravity:

The gravitational law was proposed by Newton in the late 16th century. This law states that:

“Each and every object in this universe attracts every other object with a certain amount of force that is directly proportional to the mass of both objects and is inversely proportional to the square of the distance among them”


Gravitational Force Formula:

The Newton’s force of gravity equation as under:

$$ F = \frac{Gm_{1}m_{2}}{r^{2}} $$


  • F = gravitational force
  • \(m_{1}\) = Mass of first object or body
  • \(m_{1}\) = Mass of second object or body
  • G = gravitational constant whose value is as follows:

$$ G = 6.67 * 10^{11} Nm^{2}kg^{-2} $$

  • \(r^{2}\) = Distance among the objects

This free gravity calculator will take instants to compute all the parameters involved in the above expression. So stop thinking too much and start calculating them without any hurdle while maintaining the precision.

Local Gravity:

This is another concept while calculating the force of gravity. Local gravitational force can be computed by using this best force of gravity calculator. But as you know, understanding manual calculations is also important. So it’s time to discuss it!

International Force of Gravity Formula(IGF):

$$ IGF = 9.780327 \left(1 + 0.0053024sin^{2}Φ – 0.0000058sin^{2}2Φ\right) $$

How To Calculate Gravitational Force?

Let’s resolve an example to understand the concept of gravity in proper detail. Stay focused!

Example # 01:

How to find gravitational force?


By using force of gravity formula, we have:

$$ F = \frac{Gm_{1}m_{2}}{r^{2}} $$

$$ F = \frac{6.67*10^{-11}*106*98}{\left(103\right)^{2}} $$

$$ F = \frac{6.67*10^{-11}*10388}{10609} $$

$$ F = \frac{69287.96*10^{-11}*10388}{10609} $$

$$ F = \frac{6.928.96*10^{-7}}{10609} $$

$$ F = \frac{6.53*10^{-11}N $$

For instance, you can also make use of the free gravitational force calculator to verify the results in a matter of seconds.

How Gravity Calculator Works?

Let’s get to know how this gravitational attraction calculator will help you to calculate entities of the gravitational force equation. Stay focused to learn better!


  • From the first drop-down list, make a selection regarding the parameter you wish to calculate
  • After you do that, write down the values of the required parameters in the designated field s
  • Also, select the units from the list
  • At last, hit the calculate button to calculate gravitational force


The free universal gravitation calculator does the following calculations:

  • Calculates the force of gravity among objects
  • Determines the mass of objects
  • Estimates the distance between the objects
  • Gives you an idea about the local gravity as well


What causes gravity?

Scientifically, the shape of the spacetime is the major factor that gives rise to the force of gravity. This statement was given by the famous scientist Einstein and you can calculate this force by using our online gravitational force calculator.

Is there gravity on the sun?

Yes, of course! This is the gravity force due to which the Sun is holding the whole Solar System. And the gravitational force of the Sun is about 274\(ms^{-2}\). You can also verify it by using our free gravity calculation in a matter of seconds.

How much gravity is 1g?

1g is known as the normal gravity. It is basically the acceleration that is caused in an object due to only gravitational pull near the surface of the earth. Its value is about 32.2\(ft*sec^{-2}\). If you want to study and understand the concept in detail, then it’s time to tap the gravitational acceleration calculator.

What will happen if there is no gravity?

If the force of gravity vanishes in the universe, each and every matter will collide with each other. If we talk about the Earth, it will stop rotating. All of us will become weightless and the atmosphere will be lost in space forever. In short, there would be an ultimate destruction without any gravitational force of attraction.

Why does gravity exist in space?

Simply, gravity is everywhere in the universe. It helps to keep the planets and stars in their particular orbits of rotation so as to keep the system running smoothly. You can determine the force of gravity for any planet or star by using this free gravity calculator.

Which planet has the most gravity?

Among the planets in our Solar System, Jupiter has the largest size and thus the highest force of gravity. If you have a certain mass of about 1 kg on the Earth, it will weigh about 3.5kg on Jupiter.

Where on Earth is there no gravity?

In California, there is a place named Mystery Spot which has gravity almost equal to zero.
It was discovered in 1939 and opened to the public in 1940. This place in the world is one of those where the gravitational laws become workless.

Does zero gravity exist?

No, it is just impossible. Gravity is everywhere that keeps the galaxies, black holes, and planets revolving in the orbits.

What if we lost gravity for 5 seconds?

If the gravitational force disappears for 5 seconds on the Earth, it will end life on the planet.

Is gravity really just time?

Scientific research reveals that gravity is the curving of time and space into one another. The stronger the gravity force, the more the space time curve is.

Can gravity bend light?

Yes, gravity can bend the light for sure. A physical phenomenon as gravitational lensing glossary explains all the important aspects of light bending due to gravity. And when it comes to how to calculate gravity for it, you can trust our free gravitational force calculator.


The concept of gravity is very important as it is the basic phenomenon of life existence on Earth. That is why we have developed this free gravitational constant calculator so that you could understand the concept in proper detail.
