PHYS 2070: General Physics I

Unlock the secrets of calculating electric charge using Coulomb's Law and discover the fascinating world of electrostatic forces. Learn how to determine the charge on two spheres, spaced 20.0 cm apart, and understand the role of elementary particles in this physics tutorial.

Explore the intricate dynamics of an L-C circuit as we analyze voltage current and energy transitions between a 60.0 millihenry inductor and a 250 microfarad capacitor. Understand the principles of energy transfer and storage in this system. Uncover key insights from calculations on capacitor charges and inductor energies at specific circuit conditions.

Discover the gravitational forces at play in a triangle of masses in this video. We calculate the net force on each mass and explore how changing the side length impacts these forces. Join us for a gravitational journey through physics.

Step into the thrilling world of amusement park divers as we explore the physics behind their jaw-dropping stunts. Diving from a platform 21.3 meters (70 feet) above a pool of water, we investigate the announcer's claim that divers enter the water at a speed of 56 miles per hour (25 meters per second). We'll also uncover the possibility of divers leaping directly upward to achieve a specific water entry speed and examine the physical feasibility of such a feat. Join us for an educational journey
