Why is gravitation called universal law?

Question

Answer

It is called so because it is applicable on all bodies having mass, and the bodies will be governed by the same law, that is newton's law of gravitation. Thus, as it is applicable universally, it iscalled as universal law.

Answer

Because it is applicable on all bodies having mass in universe, therefore, it is also called universal law.

I hope it helps you!!!!

Answer

Introduction:
Gravitation is referred to as a universal law because it applies to all objects in the universe. It is a fundamental force that governs the motion and interaction of celestial bodies, from the smallest particles to the largest galaxies. This law was first formulated by Sir Isaac Newton in the late 17th century and is still widely accepted today due to its universal applicability and accuracy in describing the behavior of objects in space.

Key Points:
Gravitation as a Universal Force can be explained through the following key points:

1. Every object with mass attracts every other object with mass:
- According to Newton's law of universal gravitation, every object in the universe attracts every other object with a force that is directly proportional to the product of their masses.
- This means that no matter how small or large an object is, it exerts a gravitational force on other objects around it.

2. Inverse square law:
- Gravitational force decreases with distance according to the inverse square law. This means that as the distance between two objects increases, the gravitational force between them decreases by the square of the distance.
- For example, if the distance between two objects is doubled, the gravitational force between them becomes four times weaker.

3. Planetary motion:
- Gravitation explains the motion of planets around the Sun. The gravitational pull of the Sun keeps the planets in their orbits.
- This was mathematically described by Johannes Kepler's laws of planetary motion, which were later explained by Newton's law of gravitation.

4. Universal applicability:
- Gravitation is not limited to objects in our solar system; it applies to all objects in the universe, regardless of their size or distance from each other.
- It is responsible for the formation and behavior of galaxies, stars, and other celestial bodies.

5. Predictive power:
- The universal law of gravitation has been extensively tested and verified through experiments and observations.
- It accurately predicts the motion of planets, the orbits of satellites, and the behavior of objects in space.

Conclusion:
Gravitation is rightly called a universal law because it applies to all objects in the universe and governs their motion and interaction. It is a fundamental force that plays a crucial role in understanding the dynamics of celestial bodies and has been extensively tested and verified. From the motion of planets to the behavior of galaxies, the universal law of gravitation provides a comprehensive framework for understanding the workings of the universe.
