PHYS 11400: Professional Physics and Astronomy Seminar 1

In this enlightening video, we unravel the mysteries of electric charges and forces. Discover the fascinating concept of how the separation between two identical tiny spheres, each carrying the same electric charge, influences the force they exert on each other. Will the force double, become one-quarter as large, or remain unchanged? Join us to explore the intriguing world of electrostatics and the principles that govern electric interactions.

Discover the limits of circular motion as we explore the maximum speed a ball can achieve before its string breaks. Uncover the physics behind this thrilling scenario in our engaging video.

Explore the concept of capacitance and learn how to calculate potential difference, the impact of separation, and the work required for a parallel-plate air capacitor.

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.

Explore the fascinating world of electric potential as we calculate the value at the center of a circular arrangement of five equally charged particles. Join us for a captivating journey into electrostatics and symmetry in this enlightening video.

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.
