PHI 2010: Introduction to Philosophy

Discover the physics behind violin string tension and the angle-dependent force required when pushing it against the neck. Explore how the angle affects the force needed.

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 this video we tackle the real-world physics problem of calculating the spring constant for a fisherman's scale along with the amplitude and frequency of its vibrations when a fish is added. We use Hooke's Law to find the spring constant and then apply oscillation formulas to determine the amplitude and frequency of the fish's vibrations

Explore the physics behind calculating the velocity of pebbles thrown by Romeo to hit Juliet's window with only a horizontal component.

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.
