PHYS 420001: Electricity and Magnetism

Explore the intriguing interplay of Earth's elliptical orbit, the changing seasons, and the gravitational forces it exerts on the Sun. We'll provide insights into the ratio of these forces and challenge you to consider multiple perspectives on this celestial phenomenon.

Join us to unravel the mystery of oscillations! In this video, we'll determine the period of a mass oscillating with a 0.2 m displacement and 1.2 m/s maximum speed. Explore the physics behind periodic motion and discover the key to calculating its period. Dive into the world of harmonic motion with us!

Dive into the physics of cliff jumping as we analyze the splashdown speeds of two adventurous youngsters. Explore the factors that determine their speeds and choose the best explanation among the options provided.

Explore the concept of capacitance in a spherical capacitor and learn how to calculate it. Discover how to find the plate area for a parallel-plate capacitor with the same capacitance and separation.

In an elevator ascending, an occupant drops a coin, which accelerates at a different rate than expected. This reveals the elevator's own acceleration towards the Earth. By analyzing forces and tensions, we determine the cable's tension to be 16000 N.

Analyze the physics of a falling squirrel, calculating its velocity upon hitting the ground and the deceleration due to limb bending.
