PHYS 111: Astronomy

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.

Unlock the world of electrical circuits and light intensity! In this video, we explore a circuit with three lights connected in parallel, featuring an open switch. Discover what happens to the intensity of each light when the switch is closed. Join us for a journey through electrical concepts and enlightening explanations.

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

Discover the significance of models in the fascinating realms of relativity and quantum mechanics, where conditions defy our everyday experience. Explore the concept of a model and its role in understanding these complex theories.

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

Explore the fundamental concept of work in physics and discover the key conditions, including movement, net force, opposing force, and direction, that must be met for work to be accomplished when pushing on an object, such as a rock.
