Apparent Weightlessness Introduction

The video tutorial explores the concept of gravity, starting with the equation for gravitational force on Earth. It discusses conditions for zero gravity, derives the acceleration due to gravity, and explains weightlessness in space. The tutorial calculates gravity on the International Space Station, clarifying why astronauts appear weightless. It introduces the concept of apparent weightlessness, using examples like a falling bucket of water and free-falling elevators to illustrate the phenomenon.

How does the falling of the International Space Station relate to its orbit around the Earth?
