PHYS 105: Conceptual Physics

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.

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 fascinating comparison between the acceleration of a motorcycle going from 80 km/h to 90 km/h and a bicycle accelerating from rest to 10 km/h in the same time frame.

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!

Explore the fundamental principles of this law, unraveling its implications, and clarifying common misconceptions related to mass preservation in chemical reactions.

Explore the fascinating world of geosynchronous satellites in this video. Learn how these communication satellites are strategically placed in circular orbits, staying directly over fixed points on the Earth's equator as our planet rotates. We delve into the physics behind these orbits, calculating the speed and acceleration of a satellite in geosynchronous orbit, using the Earth's radius and altitude as reference. Gain a deeper understanding of the science that enables global communications.
