PHYS 140: General Physics 1

Explore the nuances of Newton's third law and learn how the choice of the 'system of interest' influences force pair cancellation.

Explore the physics behind a water-skier accelerating from an initial speed to a faster one. Learn how to calculate the work done using the change in kinetic energy. Understand the principle of energy conservation through real-world examples.

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.

Join us for an engaging exploration of projectile motion as we dissect a fascinating scenario. We delve into the physics of a projectile fired with an initial speed of 36.6 m/s at an angle of 42.2° above the horizontal on a flat firing range. Discover how to determine the maximum height, total time in the air, total horizontal distance covered (range), and the speed of the projectile 1.50 seconds after firing. This video will demystify the dynamics of projectiles in a clear and educational manne

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.

Uncover the fascinating science behind peephole lenses, including the principles of light refraction and observer positioning that allow for an extensive field of vision through a hotel room door.
