PHYS 1111: General Physics

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.

Explore the intriguing interplay of Earth's elliptical orbit, the changing seasons, and the gravitational forces it exerts on the Sun. We'll provide insights into the ratio of these forces and challenge you to consider multiple perspectives on this celestial phenomenon.

Discover the gravitational forces at play in a triangle of masses in this video. We calculate the net force on each mass and explore how changing the side length impacts these forces. Join us for a gravitational journey through physics.

In this video we break down a complex physics problem about a 330-kg piano sliding down a 28° incline while a man resists its motion. We meticulously calculate the force exerted by the man work done by various forces including friction and gravity and the net work done on the piano.

Explore Earth's dimensions in this video! We calculate its circumference, surface area, and volume. Join us to understand the scope of our planet, both in its physical size and mathematical concepts.

Journey to the outer reaches of our solar system with a captivating exploration of Sedna, the most distant-known object discovered in 2003. This enigmatic celestial body boasts a 1700 km diameter, a 10,500-year orbit around the sun, and a maximum speed of 4.64 km/s. Join us as we delve into the calculations of its elliptical orbit, its minimum speed, and the intriguing variations in its kinetic energy. Uncover the mysteries of Sedna's motion in this educational video.
