Kinematics
PHYS 201 · Module 1
This module develops the calculus-based language of motion before asking what causes it. Students study one-dimensional motion, two-dimensional projectiles, and the role of reference frames in describing physical events.
Lessons in this module
1D motion with constant acceleration
Constant-acceleration motion is the foundation of many mechanics problems. This lesson derives the standard equations from calculus and explains their meaning.
2D kinematics and projectile motion
Two-dimensional motion is handled by treating position, velocity, and acceleration as vectors. Projectile motion is a key example where horizontal and vertical motion can be analyzed separately.
Relative motion and reference frames
Motion is always described relative to a frame of reference. This lesson introduces relative velocity, Galilean transformations, inertial frames, and the importance of observer perspective.
