PHYS 4: Mechanics

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.

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

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.

Understand how to determine the coefficient of kinetic friction using a wooden block and a spring. Employing the law of conservation of energy, we use the spring's compression and stretch measurements. Through energy equations and Newton's second law, we deduce that ? equals 0.4.

Uncover the fundamental base quantities of the SI system and test your knowledge with a quiz to identify which one is not considered a base quantity. Is it mass, length, energy, time, or are they all base quantities? Join us to find out!

Delve into the physics of high-speed tracks and calculate the radius where drivers experience a 5.5g acceleration, exploring the multiple options and their implications.
