PHY 161: Physics

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 physics of cliff jumping as we analyze the splashdown speeds of two adventurous youngsters. Explore the factors that determine their speeds and choose the best explanation among the options provided.

Step into the thrilling world of amusement park divers as we explore the physics behind their jaw-dropping stunts. Diving from a platform 21.3 meters (70 feet) above a pool of water, we investigate the announcer's claim that divers enter the water at a speed of 56 miles per hour (25 meters per second). We'll also uncover the possibility of divers leaping directly upward to achieve a specific water entry speed and examine the physical feasibility of such a feat. Join us for an educational journey
