PHYS 121: General Physics II

Uncover the science behind a common sensation - why hot concrete feels hotter than a rug at the same temperature on a scorching summer day. We'll explore the factors at play in this intriguing phenomenon and provide a clear understanding of the science behind it.

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.

Join us in a lunar leap! We estimate how gravity affects jumping distance on the Moon compared to Earth, with the same takeoff speed and angle. Explore the moon's reduced gravity and its impact on human capabilities.

Join us for a dramatic river rescue mission! In this video, we solve the problem of how a rescue team can reach a child in danger of drowning in a fast-flowing river. We calculate the angle from the shore for their pilot to approach the child directly, considering the river's current and the boat's speed. Explore the principles of vector addition and save lives!

Explore the fascinating optical phenomena involving a cat, a converging lens, and the creation of virtual and real images.

Analyze the physics of a falling squirrel, calculating its velocity upon hitting the ground and the deceleration due to limb bending.
