PHYS AND ASTRO 218: General Physics

Explore the world of collectible stamps as we delve into the story of the rare 1918 'Jenny' stamp and its astonishing auction price. Join us to learn about the use of a simple magnifying glass to examine this valuable collectible and discover how to calculate its focal length.

Join us on the baseball field as we calculate the physics of a ground ball throw to second base. In this video, we determine the distance from the shortstop to the second baseman and the vertical drop of the ball. Explore the principles of projectile motion in sports.

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.

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.

Discover the perfect golf shot! We calculate the height of the tallest tree a golf ball must clear to achieve the longest possible hole-in-one. Explore the physics and precision of golf's ultimate achievement.
