PHY 121: Physics 1

Dive into the world of projectile motion as we calculate the horizontal and vertical distances a launched projectile covers. Explore the impact of angle and speed on the trajectory, all explained in this engaging video.

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.

Explore Earth's dimensions in this video! We calculate its circumference, surface area, and volume. Join us to understand the scope of our planet, both in its physical size and mathematical concepts.

In this video, we explore the concept of time and distance as we compare two cars traveling at different speeds along a straight highway. We'll calculate when the faster car arrives at a destination 16 km away and find out how far they must travel for it to arrive 15 minutes before the slower car. Join us for an engaging journey through the world of physics and velocity!

Delve into Newton's third law of motion and explore how the choice of the 'system of interest' influences whether force pairs cancel each other out.
