PHY 162: General Physics II

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.

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.

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.

Explore the fundamental principles of this law, unraveling its implications, and clarifying common misconceptions related to mass preservation in chemical reactions.

Join us to explore the science of hand-warming through friction in this video. We calculate the temperature increase as a woman rubs her hands together, converting work into thermal energy. Dive into the physics of heat generation and discover how friction can keep you warm.

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.
