Gravitational Force Formula

According to Newton, every object with more than zero mass pulls on every other object in the universe. Planets, stars, galaxies, and even light are all pulled to one other by gravity.

You can use this gravitational force calculator to determine how much force there is between any two things you choose. Read on to learn more about the importance of the gravity force formula and use it. 

What is Gravitation?

All the things on earth are attracted to each other by gravity, also called gravitation. According to Newton’s law of universal gravitation, this universal force of attraction is at work on everything on the earth. All things with mass or energy, like planets, stars, galaxies, and even the light itself, are drawn to each other. This is a natural occurrence. 

There are two types of gravity. The earth’s gravity determines how heavy everything is, and the moon’s gravity causes ocean tides. Attraction is how bodies from different objects pull on each other because they are so big. SI unit of gravity is m/s2

Gravitational Force is the force that makes things move.

In general, any two objects with a certain mass will attract each other. People call gravitational forces attractive because they always pull groups together but never pull them apart from each other, which makes them seem like they’re good at pulling things together. Here, we can see that every object in the universe, including us, is pulling on every other entity.

Gravitational force is one of nature’s most influential forces. People always find it appealing because it is a natural force that works between two bodies, and it pulls things toward the center of the earth. 

Properties of Gravitational Force

  • Long-range force: The gravitational force is a long-range force that exists between two objects without taking into account the medium that separates them, like the earth.

  • You need two things with many masses every day to get gravitational force. When something has more weight, it will be stronger. This means that an object with more weight will have more energy.

  • Following the inverse square law, the force changes as the square root of the number of forces. Because the gravitational force changes with the square of the distance between two objects, the more space between them, the less pressure.

  • g= 9.8 m/s2 is how fast you move on the earth’s surface because of the gravitational force.

  • When two things are near each other, the gravitational force always brings them together and never pushes them apart.

  • The gravitational force is always the same, no matter what separates them.

  • The gravitational force is the least powerful of the four fundamental forces.

  • In this case, the gravitational force always acts along the line connecting the two object’s center. This is why it is called the “central” force.

  • There is a direct relationship between the weight of objects and their gravitational force.

  • There is still a gravitational force even if the objects aren’t touching each other in real life.

Gravitational force definition

According to Newton, every object with more than zero mass pulls on every other object in the universe. Gravity is the force that pulls things together. It exists between all things, even though it may seem like a silly idea. People read these words and feel a small force between them and the computer screen as they do. If you apply the principle of gravitational force to planets or stars, the effects of this force will start to show. This force is too small to have any visible results.

Freefall is one of the most common ways to show that the gravitational force is working in this way.

The gravity equation tells you how to figure out how gravity works.

Use the following formula to figure out the gravitational force between two things.

F = GMm/R²

where:

  • For gravitational force, the letter F stands for this. When it comes to weight, it’s always positive. It means that when two objects of a certain mass come together, they always attract each other and never push each other away.

  • In this case, m and M are the masses of two objects that are in question;

  • R is the distance between the centers of these two objects.

  • People use G as a way to measure the force of gravity. It is 6.674×10-11 N·m²/kg².

Is this equation the same as the one in Coulomb’s law? It is different from Newton’s law of gravity because Coulomb’s law talks about the force between electric charges.

How to use the gravity formula?

1. Find out the weight of the first thing. Earth has a mass of 5.972×1024 kg. Let’s pick it. In the calculator, you can type 5.972e24 to get this huge number.

2. Make sure you know how much the second thing weighs. Choose the Sun. It weighs 1.9891030 kg, which is about 330,000 Earths.

3. Determine how far two things are apart from each other. In this case, we will choose the distance from Earth to the Sun. This distance is about 149,600,000 km.

4. This is how you use the gravitational force calculator. Enter these values. It will use the gravity equation to determine how much force it has.

5. You can now read the results. This is how it works. For example, the force between the Earth and the Sun is 3.541022 N, which is very strong.

Conclusion

Gravitation is a force between two objects. There is a force between every particle in the universe that is directly proportional to the sum of their masses and inversely proportional to the square of their distance. As a result, the gravitational force depends on how much mass each body has and how far apart they are. This article has provided adequate information on the gravitational force formula for class 11 and should help with exam preparation.
