PHYS 111: Introductory Physics

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.

Learn how to determine the hot resistance and current in the electrical system of older cars with a 6.00-V voltage supply.

Step into the showroom as we explore the intriguing connection between rug dimensions and area. Learn whether a rug being twice as long as another implies its area is also doubled. Join us for a comprehensive explanation of this geometric concept.

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

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.

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.
