explain gravitational force by giving a suitable example
Answers
Answer:
The gravitational force is a force that attracts any two objects with mass. ... This is called Newton's Universal Law of Gravitation. for example : when U throw a ball upwards it came back downwards because of the gravitational force acting on it.Gravity, or gravitation, is a natural phenomenon by which all things with mass are brought toward one another, including objects ranging from atoms and photons, to planets and stars
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 force, 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.
for example : when U throw a ball upwards it came back downwards because of the gravitational force acting on it.
Universal Gravitation Equation
This equation describes the force between any two objects in the universe:
f = (g m1m2)\div r \times r
In 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 : 6.67 × 10-¹¹
m1 is the mass of one object (measured in kilograms, kg)
m2 is the mass of the other object (measured in kilograms, kg)
r is the distance those objects are apart (measured in meters, m)
So if you know how massive two objects are and how far they are apart, you can figure out the force between them.

Answer:
gravitational force is a force it pull ever thing towards the ground or towards the earth
for ex= An apple fall down from a tree
