PHYS 105: Classical Mechanics

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.

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.

Explore the concept of capacitance in a spherical capacitor and learn how to calculate it. Discover how to find the plate area for a parallel-plate capacitor with the same capacitance and separation.

Discover the math behind car spring oscillations when driving over bumps. Understand how a car's weight and driver affect the spring constant and resulting frequency. Grasp the interplay of forces and how they dictate harmonic motion.

In this educational video, we dive into the concept of volume and its units. We explore the correct units for measuring volume and discuss the common misconception that a cylinder's volume is given by ?r^3h. Join us for a comprehensive explanation of the fundamentals of volume measurement and understand why the given formula doesn't hold.
