PHYS 150: How Things Work

Delve into Newton's third law of motion and explore how the choice of the 'system of interest' influences whether force pairs cancel each other out.

Join us in exploring the concept of significant figures in numerical values. Learn to identify and count significant figures in various numbers, from whole numbers to decimals. Understand the precision and accuracy of your measurements through this engaging video.

Discover the impact of a 0.09-N thrust engine on a 480 kg spacecraft's speed during 1 week of maximum power operation. Uncover the assumptions involved in this space physics scenario.

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.

Join us as we delve into the physics of a monkey and her cart, complete with a spring. Witness the intriguing change in maximum speed when the monkey picks up a cantaloupe. Learn how mass and vibrations affect the outcome.

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