Variable Mass Systems: Rocket Example

This lecture covers the concept of variable mass systems using the example of a rocket. It explains the calculation of the rocket's velocity at a given time in a constant gravitational field, considering the mass variation due to fuel consumption. The lecture also discusses the momentum variation, neglecting air resistance and assuming a Galilean reference frame. The integration of momentum over time is demonstrated to find the final velocity of the rocket. Additionally, the lecture explores the propulsion mass difference between the full and empty rocket, providing numerical values for a specific rocket example.
