# Define/explain this gravity calculation (picture)

• nukeman
In summary, the conversation is about finding a suitable graphic or image for calculations involving acceleration and gravity. The image shared is a description of Newton's law of gravity, stating that the force due to gravity is equal to the product of the masses and the square of the distance between them. It is mentioned that this is not a homework question and that the objects may experience different accelerations if they have different masses.

Hey guys,

Im trying to write something up, and I want a more detailed explanation of this calculation (image below) - Can anyone give it a go? Thanks in advance

I am trying to find a graphic/image that best suits calculations that have to do with acceleration and gravity, so if anyone has one, please do share! THanks

P.S. - This is not a homework question

Thanks

That is an incredibly simple 'calculation,' its basically just a definition. You're going to have to be more specific on what you're looking for.

The picture is simply a description of Newton's law of gravity.

it says that the force due to gravity each ball experiences is equal to the product of their masses over the square of the distance separating them.

note that each object experiences the same force but does not experiences the same acceleration IF they are of different masses.

It is easier to conceptualize if you reduce them to point sources, which is the usual practice.

## What is gravity calculation?

Gravity calculation refers to the process of determining the force of gravity between two objects. It is a mathematical calculation that takes into account the masses and distances of the objects.

## How is gravity calculated?

Gravity is calculated using the formula F = G * (m1 * m2)/d^2, where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and d is the distance between them. This formula was derived by Sir Isaac Newton and is known as the Law of Universal Gravitation.

## What is the purpose of gravity calculation?

The purpose of gravity calculation is to understand and predict the motion of objects in the presence of gravity. It is used in various fields such as astronomy, physics, and engineering to study the interactions between objects and their gravitational forces.

## How is gravity calculation used in everyday life?

Gravity calculation is used in everyday life in many ways. For example, it is used in the design of buildings and structures to ensure they can withstand the force of gravity. It also plays a crucial role in the motion of objects such as planets, satellites, and projectiles.

## What are the limitations of gravity calculation?

Gravity calculation is based on the assumption that the two objects are point masses and that there are no other external forces acting on them. This is not always the case in real-life situations, which can lead to some inaccuracies in the calculations. Additionally, the formula does not account for the effects of other forces, such as air resistance, which can also impact the motion of objects.
