Kinematics of Point Particles

This lecture covers the definitions, properties, and notation related to point particles in a reference frame. It discusses concepts such as position vectors, trajectories, velocity vectors, and acceleration vectors. The lecture also explores the Galilean principle and the unit tangent vector. It delves into the relationship between velocity, acceleration, and the curvature of trajectories, emphasizing the centripetal acceleration. The lecture concludes with a summary of the key concepts discussed, highlighting the importance of understanding the kinematics of point particles.
