PHYS 235: Modern Physics

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.

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.

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

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.

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.
