PHY 251: Introduction to Condensed Matter Physics

Dive into the world of aviation as we calculate the thrust required for a medium-sized jet to maintain a cruising speed of 230 m/s at a specific altitude. Explore the impact of air density and drag coefficients on aircraft performance.

Unlock the secrets of calculating electric charge using Coulomb's Law and discover the fascinating world of electrostatic forces. Learn how to determine the charge on two spheres, spaced 20.0 cm apart, and understand the role of elementary particles in this physics tutorial.

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.

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

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.
