PHYS 2022: Stars, Galaxies and the Universe

Explore the fascinating science of air temperature change in this video! We calculate how the volume of inhaled air increases as it warms from 0.0°C to body temperature. Discover the principles of thermal expansion in the human body.

Discover the physics behind violin string tension and the angle-dependent force required when pushing it against the neck. Explore how the angle affects the force needed.

In an elevator ascending, an occupant drops a coin, which accelerates at a different rate than expected. This reveals the elevator's own acceleration towards the Earth. By analyzing forces and tensions, we determine the cable's tension to be 16000 N.

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.

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.

Explore the physics of a light-rail commuter train's motion. Understand how to calculate times for acceleration and deceleration using the equations of motion. Dive into the concept of emergency deceleration and its implications.
