PH 122: General Physics II

Embark on a celestial journey! In this video, we calculate the altitude above a distant planet's surface where a starship orbits. Discover how astronauts experience reduced free-fall acceleration and the fascinating dynamics of space travel.

Discover the physics behind violin string tension and the angle-dependent force required when pushing it against the neck. Explore how the angle affects the force needed.

Explore the fascinating world of electric potential as we calculate the value at the center of a circular arrangement of five equally charged particles. Join us for a captivating journey into electrostatics and symmetry in this enlightening video.

Step into the thrilling world of amusement park divers as we explore the physics behind their jaw-dropping stunts. Diving from a platform 21.3 meters (70 feet) above a pool of water, we investigate the announcer's claim that divers enter the water at a speed of 56 miles per hour (25 meters per second). We'll also uncover the possibility of divers leaping directly upward to achieve a specific water entry speed and examine the physical feasibility of such a feat. Join us for an educational journey

Explore the profound link between these two fundamental concepts in physics, and understand how they relate through the Work-Energy Theorem.

Join us on an exciting lunar adventure as we explore the descent of a lunar lander towards the moon's surface. We'll unravel the physics behind its journey using the equation y(t) = b - ct + dt^2, and answer questions about the lander's initial and final velocities. Get ready to explore the dynamics of space exploration and lunar landings in this informative video!
