PHYS 1430: Mechanics

Uncover the fascinating science behind peephole lenses, including the principles of light refraction and observer positioning that allow for an extensive field of vision through a hotel room door.

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.

In an elevator ascending, an occupant drops a coin, which accelerates at a different rate than expected. This reveals the elevator's own acceleration towards the Earth. By analyzing forces and tensions, we determine the cable's tension to be 16000 N.

Join us as we delve into the physics of a monkey and her cart, complete with a spring. Witness the intriguing change in maximum speed when the monkey picks up a cantaloupe. Learn how mass and vibrations affect the outcome.

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.
