PHYS 1080: Physics and the Universe

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.

Delve into the physics of high-speed tracks and calculate the radius where drivers experience a 5.5g acceleration, exploring the multiple options and their implications.

Explore the nuances of Newton's third law and learn how the choice of the 'system of interest' influences force pair cancellation.

Explore the physics of a tennis ball hitting a wall and its momentum changes. Learn about the original momentum, changes, and the concept of reference objects in this engaging video.

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.

Explore how a mass spectrometer works by analyzing an ion's path through the device. Understand the relationship between electric and magnetic fields in determining the ion's trajectory. Learn to compute the radius of an ion's path within the mass spectrometer.
