PHYS 221: General Physics I

Illuminate the science of flashlight power! In this video, we explore how a 6V bulb is powered by a 3V battery with an internal resistance. We calculate the power dissipation of the bulb and the terminal voltage of the battery, unraveling the physics of electrical circuits.

Explore the intriguing interplay of electric fields and conductors in this video. We examine how the presence of a point charge inside or outside a conductor affects the electric field. Join us to unravel the principles of electrostatics.

Discover the significance of models in the fascinating realms of relativity and quantum mechanics, where conditions defy our everyday experience. Explore the concept of a model and its role in understanding these complex theories.

Discover the incredible tale of David Purley's survival in a high-speed car crash! In this video, we calculate the magnitude of the acceleration he experienced during the rapid deceleration from 173 km/h to zero. Learn how to express it in units of gravity and explore the limits of human endurance.

Discover the key reasons why measurement standards rooted in laboratory procedures offer advantages over standards based on specific objects, like the international prototype kilogram. Dive into the world of metrology and standardization in this informative video.

Uncover the secrets of watch crystals in this video! We convert the frequency of a quartz crystal used in electric watches into its period. Join us to explore the principles of timekeeping and crystal oscillations.
