PH 121: General Physics I (GT-SC1)

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

Unlock the secrets of battery performance in this video! We calculate the terminal voltage for a battery with internal resistance, connected in series with resistors of different values. Explore the effects of resistance on voltage in electrical circuits.

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 fascinating world of geosynchronous satellites in this video. Learn how these communication satellites are strategically placed in circular orbits, staying directly over fixed points on the Earth's equator as our planet rotates. We delve into the physics behind these orbits, calculating the speed and acceleration of a satellite in geosynchronous orbit, using the Earth's radius and altitude as reference. Gain a deeper understanding of the science that enables global communications.

Explore the fascinating optical phenomena involving a cat, a converging lens, and the creation of virtual and real images.

Uncover the fundamental base quantities of the SI system and test your knowledge with a quiz to identify which one is not considered a base quantity. Is it mass, length, energy, time, or are they all base quantities? Join us to find out!
