Answers
- The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. In fact, every object, including you, is pulling on every other object in the entire universe!
Explanation:
What is the Gravitational Force?
The universe has a lot of forces, a lot of pushes and pulls. We're always pushing or pulling something, even if only the ground. But it turns out that in physics, there are really only four fundamental forces from which everything else is derived: the strong force, the weak force, the electromagnetic for%ce, and the gravitational force.
The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. In fact, every object, including you, is pulling on every other object in the entire universe! This is called Newton's Universal Law of Gravitation. Admittedly, you don't have a very large mass and so, you're not pulling on those other objects much. And objects that are really far apart from each other don't pull on each other noticeably either. But the force is there and we can calculate it.

Universal Gravitation Equation
This equation describes the force between any two objects in the universe:
Universal Gravitation Equation
Universal Gravitation EquationIn the equation:
- F is the force of gravity (measured in Newtons, N)
- G is the gravitational constant of the universe and is always the same number
- M is the mass of one object (measured in kilograms, kg)
- m is the mass of the other object (measured in kilograms, kg)
- r is the distance those objects are apart (measured in meters, m)I hope this is help you
