PHYS 20246: General Physics 2

Explore the fascinating world of geosynchronous satellites in this video. Learn how these communication satellites are strategically placed in circular orbits, staying directly over fixed points on the Earth's equator as our planet rotates. We delve into the physics behind these orbits, calculating the speed and acceleration of a satellite in geosynchronous orbit, using the Earth's radius and altitude as reference. Gain a deeper understanding of the science that enables global communications.

Discover the limits of circular motion as we explore the maximum speed a ball can achieve before its string breaks. Uncover the physics behind this thrilling scenario in our engaging video.

Explore the effects of altitude change on a pendulum clock's speed when moved from the Mississippi Delta to the Rocky Mountains. Learn why it runs faster or slower and how to make adjustments. Discover the assumptions involved in this fascinating timekeeping scenario.

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.

Explore the fascinating world of friction in motion! In this video, we delve into the concept of frictional forces as we examine a crate being pushed across a factory floor. We'll calculate the magnitude and direction of the frictional force and uncover its role in maintaining constant velocity. Discover the science behind everyday motion.
