PHYS 100: Cosmology

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.

Explore the effects of altitude change on a pendulum clock's speed when moved from the Mississippi Delta to the Rocky Mountains. Learn why it runs faster or slower and how to make adjustments. Discover the assumptions involved in this fascinating timekeeping scenario.

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

Learn how to determine the hot resistance and current in the electrical system of older cars with a 6.00-V voltage supply.

Discover the gravitational forces at play in a triangle of masses in this video. We calculate the net force on each mass and explore how changing the side length impacts these forces. Join us for a gravitational journey through physics.
