PHYS 72109: General Physics

Discover the fascinating world of Slinky physics as we explore the speed of transverse waves when this iconic toy is stretched by a 2.0-N force. Dive into the science behind the Slinky's behavior!

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.

Discover the physics behind the angle formed by loosely hanging hand straps on a streetcar negotiating a curved turn.

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.

Discover how to calculate rope tension with an object hanging in the center. Understand the relationship between the sag, the weight of the object, and the tension. Convert the result into kilonewtons for easy reference.

Learn how to calculate total displacement when traveling west and south at different speeds and durations. Explore the direction and magnitude of your journey in this informative video.
