PHYS 101: General Physics I

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 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.

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.

Using a cube measuring 28.0 cm per side, we calculate its total electric flux. Through Gauss's law, we determine the box's enclosed charge. The resultant enclosed charge is 9.77 x 10?? C.

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.

Unpack the concept of normal force on a sports car and its driver atop a hill. Utilize Newton's second law to calculate these forces based on speed and hill curvature. Discover the speed at which the driver feels weightless in the car.
