Acceleration: Motion in the Plane

This lecture covers the concepts of velocity and acceleration in the context of motion in the plane. It explains the difference between instantaneous and average velocity, as well as instantaneous and average acceleration. The lecture also discusses how acceleration is related to changes in velocity over time, emphasizing the direction and magnitude of acceleration vectors. Examples are provided to illustrate how acceleration affects the motion of objects, particularly in scenarios like projectile motion and free fall due to gravity.
