PHYS 2054: Physics 2

Unlock the world of electrical circuits and light intensity! In this video, we explore a circuit with three lights connected in parallel, featuring an open switch. Discover what happens to the intensity of each light when the switch is closed. Join us for a journey through electrical concepts and enlightening explanations.

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 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.

Uncover the fascinating science behind peephole lenses, including the principles of light refraction and observer positioning that allow for an extensive field of vision through a hotel room door.
