PHYS 140: General Physics

Illuminate the science of flashlight power! In this video, we explore how a 6V bulb is powered by a 3V battery with an internal resistance. We calculate the power dissipation of the bulb and the terminal voltage of the battery, unraveling the physics of electrical circuits.

Dive into the world of buoyancy and density in this video! We explore how an object's weight changes when immersed in water and oil. Join us to calculate the density of the object and the oil, unraveling the principles of fluid dynamics and buoyant forces.

Explore the concept of capacitance and learn how to calculate potential difference, the impact of separation, and the work required for a parallel-plate air capacitor.

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.

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.

Join us as we unravel the incredible journey of a shearwater seabird in an astonishing experiment. This remarkable bird was taken from its nest, flown 5150 kilometers away, and then successfully found its way back home 13.5 days later. We explore the concept of average velocity for both the return flight and the entire episode, shedding light on the bird's navigation prowess. Discover the fascinating world of animal navigation and physics in this captivating video.
