PHYS 133: Introduction to Astronomy

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.

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

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

Explore the fascinating science of air temperature change in this video! We calculate how the volume of inhaled air increases as it warms from 0.0°C to body temperature. Discover the principles of thermal expansion in the human body.

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 concept of capacitance in a spherical capacitor and learn how to calculate it. Discover how to find the plate area for a parallel-plate capacitor with the same capacitance and separation.
