Kinematics of Point Particle

This lecture covers the kinematics and dynamics of a point particle, including concepts such as position vector, velocity vector, acceleration vector, laws of Newton, trajectory, reference frame, and coordinate systems. The instructor emphasizes the idealization of reality in modeling point particles and the importance of understanding the causes of motion. Various examples are used to illustrate trajectories, from straight lines to complex curves. The lecture also delves into the measurement of velocity using photoelectric cells and the derivation of acceleration from the velocity vector. Students will gain a solid foundation in the fundamental principles governing the motion of point particles.
