PHYS 105: General Physics

In this educational video, we dive into the concept of volume and its units. We explore the correct units for measuring volume and discuss the common misconception that a cylinder's volume is given by ?r^3h. Join us for a comprehensive explanation of the fundamentals of volume measurement and understand why the given formula doesn't hold.

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.

Discover the incredible tale of David Purley's survival in a high-speed car crash! In this video, we calculate the magnitude of the acceleration he experienced during the rapid deceleration from 173 km/h to zero. Learn how to express it in units of gravity and explore the limits of human endurance.

Analyze the physics of a falling squirrel, calculating its velocity upon hitting the ground and the deceleration due to limb bending.

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.

Learn how to calculate total displacement when traveling west and south at different speeds and durations. Explore the direction and magnitude of your journey in this informative video.
