PHYS 120: Energy and Technology

Discover the key reasons why measurement standards rooted in laboratory procedures offer advantages over standards based on specific objects, like the international prototype kilogram. Dive into the world of metrology and standardization in this informative video.

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.

Watch as we explore the fascinating world of thermal expansion in this video. We start with a glass filled to the brim with 350.0 mL of water at a scorching 100.0°C, and then witness the magic unfold as the temperature decreases to a cool 20.0°C. But the real question is, how much more water can we add to the glass? Join us to find out!

Join us in a lunar leap! We estimate how gravity affects jumping distance on the Moon compared to Earth, with the same takeoff speed and angle. Explore the moon's reduced gravity and its impact on human capabilities.

Join us to explore the science of hand-warming through friction in this video. We calculate the temperature increase as a woman rubs her hands together, converting work into thermal energy. Dive into the physics of heat generation and discover how friction can keep you warm.
