PHYS 111: General Physics I (PHY 111)

Discover the physics behind violin string tension and the angle-dependent force required when pushing it against the neck. Explore how the angle affects the force needed.

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.

Discover how to calculate rope tension with an object hanging in the center. Understand the relationship between the sag, the weight of the object, and the tension. Convert the result into kilonewtons for easy reference.

In an elevator ascending, an occupant drops a coin, which accelerates at a different rate than expected. This reveals the elevator's own acceleration towards the Earth. By analyzing forces and tensions, we determine the cable's tension to be 16000 N.

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.

Discover how to optimize the launch tube acceleration to achieve the maximum height and earn the most points in your laboratory experiment.
