PHYS 221: Physics 221

In this video, we explore the concept of time and distance as we compare two cars traveling at different speeds along a straight highway. We'll calculate when the faster car arrives at a destination 16 km away and find out how far they must travel for it to arrive 15 minutes before the slower car. Join us for an engaging journey through the world of physics and velocity!

Join us as we explore the dynamic world of gymnastics and the forces at play. In this video, we analyze a gymnast's routine on the rings, calculating the forces involved. Learn how the gymnast's body interacts with the rings and the floor, and discover how changes in arm angles affect the forces. Dive into the physics of human movement and gymnastics.

Dive into the world of aviation as we calculate the thrust required for a medium-sized jet to maintain a cruising speed of 230 m/s at a specific altitude. Explore the impact of air density and drag coefficients on aircraft performance.

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.

Exploring the behavior of oil and water in a U-shaped tube when a barrier is removed. Understand the impact of differing densities on fluid heights. Witness equilibrium scenarios effects of equal densities and the displacement dynamics of lighter liquids.

Uncover the secrets of watch crystals in this video! We convert the frequency of a quartz crystal used in electric watches into its period. Join us to explore the principles of timekeeping and crystal oscillations.
