PHYS 201: Fundamentals of Physics III

Join us to explore the science of hand-warming through friction in this video. We calculate the temperature increase as a woman rubs her hands together, converting work into thermal energy. Dive into the physics of heat generation and discover how friction can keep you warm.

Uncover the fundamental base quantities of the SI system and test your knowledge with a quiz to identify which one is not considered a base quantity. Is it mass, length, energy, time, or are they all base quantities? Join us to find out!

In this enlightening video, we unravel the mysteries of electric charges and forces. Discover the fascinating concept of how the separation between two identical tiny spheres, each carrying the same electric charge, influences the force they exert on each other. Will the force double, become one-quarter as large, or remain unchanged? Join us to explore the intriguing world of electrostatics and the principles that govern electric interactions.

Discover how energy conservation principles determine the velocity of a bouncing ball. Relate the ball's height and its potential and kinetic energies. Understand the velocity change upon impact and rebound.

Discover the limits of circular motion as we explore the maximum speed a ball can achieve before its string breaks. Uncover the physics behind this thrilling scenario in our engaging video.

Explore the nuances of Newton's third law and learn how the choice of the 'system of interest' influences force pair cancellation.
