PHYSICS 181: PHYSICS I-Mechanics

Learn how to determine the hot resistance and current in the electrical system of older cars with a 6.00-V voltage supply.

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.

Explore the physics of a light-rail commuter train's motion. Understand how to calculate times for acceleration and deceleration using the equations of motion. Dive into the concept of emergency deceleration and its implications.

Explore the fascinating world of friction in motion! In this video, we delve into the concept of frictional forces as we examine a crate being pushed across a factory floor. We'll calculate the magnitude and direction of the frictional force and uncover its role in maintaining constant velocity. Discover the science behind everyday motion.

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 intriguing interplay of electric fields and conductors in this video. We examine how the presence of a point charge inside or outside a conductor affects the electric field. Join us to unravel the principles of electrostatics.
