PHYS 451: Problems

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.

Discover how energy conservation principles determine the velocity of a bouncing ball. Relate the ball's height and its potential and kinetic energies. Understand the velocity change upon impact and rebound.

Learn how to compute the displacement of a ball rolling off a table using calculus. Through the integration of velocity over a specific time interval, determine the ball's position. Uncover the mathematics behind real-world motion scenarios.

Join us for an engaging exploration of projectile motion as we dissect a fascinating scenario. We delve into the physics of a projectile fired with an initial speed of 36.6 m/s at an angle of 42.2° above the horizontal on a flat firing range. Discover how to determine the maximum height, total time in the air, total horizontal distance covered (range), and the speed of the projectile 1.50 seconds after firing. This video will demystify the dynamics of projectiles in a clear and educational manne

Explore the profound link between these two fundamental concepts in physics, and understand how they relate through the Work-Energy Theorem.

Discover the significance of models in the fascinating realms of relativity and quantum mechanics, where conditions defy our everyday experience. Explore the concept of a model and its role in understanding these complex theories.
