PHYS 151: General Physics I

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!

Embark on an exhilarating downhill ski adventure! In this video, we calculate the length of the incline and the time it takes for a skier to reach the bottom. Explore the physics of skiing on inclines and the thrill of motion.

Explore the physics of a tennis ball hitting a wall and its momentum changes. Learn about the original momentum, changes, and the concept of reference objects in this engaging video.

Discover the significance of models in the fascinating realms of relativity and quantum mechanics, where conditions defy our everyday experience. Explore the concept of a model and its role in understanding these complex theories.

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.
