Lecture

Trajectory and Average Speed in Physics

Description

This lecture covers the concepts of trajectory, encounter, and average speed in physics. It explains the calculations based on given distances and radii, expressing vectors in a base, and determining apparent diameters. The lecture also discusses the significance of trajectory in determining the location of an object without considering time. It highlights the similarity of apparent diameters of the sun and moon during eclipses. The presentation progresses to discuss specific cases of objects in motion, including stationary objects and those moving regularly. The lecture concludes by explaining the concept of average speed and instantaneous speed, emphasizing the importance of understanding velocity in relation to trajectory.
