PHYS 1: Principles Physics

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 secrets of watch crystals in this video! We convert the frequency of a quartz crystal used in electric watches into its period. Join us to explore the principles of timekeeping and crystal oscillations.

Uncover the fundamental base quantities of the SI system and test your knowledge with a quiz to identify which one is not considered a base quantity. Is it mass, length, energy, time, or are they all base quantities? Join us to find out!

Explore the fundamental concept of work in physics and discover the key conditions, including movement, net force, opposing force, and direction, that must be met for work to be accomplished when pushing on an object, such as a rock.

Explore the nuances of Newton's third law and learn how the choice of the 'system of interest' influences force pair cancellation.

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.
