PHYS 154: Stars/Galax/Cosmology Lecture

Explore the physics of a tennis ball hitting a wall and its momentum changes. Learn about the original momentum, changes, and the concept of reference objects in this engaging video.

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.

In this video, we explore the concept of time and distance as we compare two cars traveling at different speeds along a straight highway. We'll calculate when the faster car arrives at a destination 16 km away and find out how far they must travel for it to arrive 15 minutes before the slower car. Join us for an engaging journey through the world of physics and velocity!

Explore the fascinating comparison between the acceleration of a motorcycle going from 80 km/h to 90 km/h and a bicycle accelerating from rest to 10 km/h in the same time frame.

Explore the physics behind calculating the velocity of pebbles thrown by Romeo to hit Juliet's window with only a horizontal component.

Discover electromagnetic induction with a rotating wire loop! In this video, we explore how a 12.0-cm-diameter wire loop generates an induced emf when it's aligned with a magnetic field in 0.20 seconds. Dive into the world of electromagnetic phenomena and uncover the average induced emf.
