PHYS 199: Physical Sci Through Inquiry

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.

Discover how to calculate rope tension with an object hanging in the center. Understand the relationship between the sag, the weight of the object, and the tension. Convert the result into kilonewtons for easy reference.

Explore the dynamics of a bead under constant force. Understand its acceleration, velocity over time, and how to calculate its kinetic energy. Witness the interplay of motion equations and real-world applications in a simple system.

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.

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.
