PHYS 2021: Statics and Dynamics

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.

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

Explore the relative strengths of two fundamental forces, the electromagnetic force and the gravitational force, in this enlightening physics tutorial. Learn about Coulomb's law and Newton's law of gravitation, and uncover the significant difference in their constants that makes the electromagnetic force much more powerful than gravity.

Explore the fascinating Doppler Effect and how it alters wave frequencies when a source or observer is in motion. Dive into the physics of frequency shift with formulas and practical examples, showcasing the significant impact of source velocity on observable frequencies.

In this educational video, we dive into the concept of volume and its units. We explore the correct units for measuring volume and discuss the common misconception that a cylinder's volume is given by ?r^3h. Join us for a comprehensive explanation of the fundamentals of volume measurement and understand why the given formula doesn't hold.
