Gravitational Pull

Gravitational pull is the force of attraction that exists between two objects due to their masses. This force is what causes objects to fall towards the Earth and is responsible for keeping the planets in orbit around the Sun.

Key Concepts

• Gravity: The force that pulls objects towards each other.
• Mass: The amount of matter in an object.
• Weight: The measure of the force of gravity on an object's mass.
• Newton's Law of Universal Gravitation: The law that describes the gravitational force between two objects.

Understanding Gravitational Pull

To understand gravitational pull, it's important to grasp the concept of gravity and how it affects objects. Gravity is a natural phenomenon by which all objects with mass are brought towards one another. The force of gravity is directly proportional to the masses of the objects and inversely proportional to the square of the distance between their centers.
