Gravity & Free Fall

The video tutorial explores the concept of gravity, starting with a simple example of a thrown ball and the forces acting on it. It delves into the universal role of gravity, explaining how it affects celestial bodies and orbits. The tutorial covers Newton's law of gravitation, highlighting the relationship between mass, distance, and gravitational force. It also explains the concept of weightlessness in space, using the space station as an example. Finally, the video introduces Einstein's theory of general relativity, which describes gravity as a distortion in space-time.
