PHYS 17200: Modern Mechanics

Embark on a celestial journey! In this video, we calculate the altitude above a distant planet's surface where a starship orbits. Discover how astronauts experience reduced free-fall acceleration and the fascinating dynamics of space travel.

Explore the world of thermal insulation and heat loss in this video. We compare single-pane and double-pane windows, calculating the heat loss ratio. Delve into the fascinating science of heat transfer and insulation factors. Join us to uncover the secrets behind energy-efficient windows.

Unlock the secrets of battery performance in this video! We calculate the terminal voltage for a battery with internal resistance, connected in series with resistors of different values. Explore the effects of resistance on voltage in electrical circuits.

Step into the showroom as we explore the intriguing connection between rug dimensions and area. Learn whether a rug being twice as long as another implies its area is also doubled. Join us for a comprehensive explanation of this geometric concept.

Estimate a car's initial speed from skid marks using physics principles. Apply Newton's Second Law and equations of motion to deduce the initial velocity. Understand the role of frictional force in car deceleration during accidents.

Explore the fascinating Doppler Effect and how it alters wave frequencies when a source or observer is in motion. Dive into the physics of frequency shift with formulas and practical examples, showcasing the significant impact of source velocity on observable frequencies.
