PHYS 102: Fundamentals of Physics

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 effects of altitude change on a pendulum clock's speed when moved from the Mississippi Delta to the Rocky Mountains. Learn why it runs faster or slower and how to make adjustments. Discover the assumptions involved in this fascinating timekeeping scenario.

Dive into the world of aviation as we calculate the thrust required for a medium-sized jet to maintain a cruising speed of 230 m/s at a specific altitude. Explore the impact of air density and drag coefficients on aircraft performance.

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.

Uncover the science behind a common sensation - why hot concrete feels hotter than a rug at the same temperature on a scorching summer day. We'll explore the factors at play in this intriguing phenomenon and provide a clear understanding of the science behind it.

Unlock the secrets of battery performance in this video! We calculate the terminal voltage for a battery with internal resistance, connected in series with resistors of different values. Explore the effects of resistance on voltage in electrical circuits.
