Friction and Ballistics

This lecture covers the equations of ballistic motion with friction, including the impact of viscous friction on the ballistic trajectory. The instructor explains the laws governing ballistic motion with and without friction, highlighting the exponential decrease in horizontal velocity due to friction. The lecture also delves into the equations of motion in the Cartesian coordinate system, emphasizing the role of frictional forces. Additionally, the concept of damping time as a phenomenological quantity is discussed. Practical experiments demonstrating the impact of viscosity on the terminal velocity and damping time of falling objects are presented.
