Gravitation Basics
1. Introduction to Gravitation
Gravitation is the force that attracts two objects with mass. We'll explore this force and its effects on objects.

2. Newton's Contribution to Gravity
Isaac Newton identified that the gravitational force attracts apples to Earth and keeps the moon in orbit.

4. Understanding Free Fall
Free fall occurs when objects move under the influence of gravitational force alone, with uniform acceleration denoted by g.

6. Weight Variation with Location
Weight varies based on location due to changes in gravitational acceleration. Mass remains constant.

7. Weight on the Moon
Weight on the Moon is 1/6th of the weight on Earth due to its smaller mass and gravitational force.

9. Understanding Buoyancy
Buoyant force is exerted by a fluid upward on an immersed object. It depends on the fluid's density.

10. Archimedes' Principle
A body immersed in fluid experiences an upward buoyant force equal to the weight of the fluid displaced.
