PHYS 220: Physics

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.

Discover the physics behind the musical notes produced when car tires interact with highway lane dividers. This video explains the "stick-slip friction" phenomenon and its relation to tire vibrations. Learn how analyzing sound frequencies can offer insights into vehicle speeds

Explore the world of collectible stamps as we delve into the story of the rare 1918 'Jenny' stamp and its astonishing auction price. Join us to learn about the use of a simple magnifying glass to examine this valuable collectible and discover how to calculate its focal length.

In an elevator ascending, an occupant drops a coin, which accelerates at a different rate than expected. This reveals the elevator's own acceleration towards the Earth. By analyzing forces and tensions, we determine the cable's tension to be 16000 N.

Explore the fascinating science of air temperature change in this video! We calculate how the volume of inhaled air increases as it warms from 0.0°C to body temperature. Discover the principles of thermal expansion in the human body.

In this video we break down a complex physics problem about a 330-kg piano sliding down a 28° incline while a man resists its motion. We meticulously calculate the force exerted by the man work done by various forces including friction and gravity and the net work done on the piano.
