PHYSICS 120: ASTR 120 the Solar System

Explore the effects of altitude change on a pendulum clock's speed when moved from the Mississippi Delta to the Rocky Mountains. Learn why it runs faster or slower and how to make adjustments. Discover the assumptions involved in this fascinating timekeeping scenario.

Explore the world of thermal insulation and heat loss in this video. We compare single-pane and double-pane windows, calculating the heat loss ratio. Delve into the fascinating science of heat transfer and insulation factors. Join us to uncover the secrets behind energy-efficient windows.

Join us in this enlightening video as we explore the fascinating world of projectiles and their optimal launch angles. We dive into the physics behind how a fixed initial speed affects the range of a projectile and why, for most angles, there are two choices that yield the same range. Delve into factors that affect an archer's ability to hit a target, including wind, and learn why a smaller angle, closer to the horizontal, is often preferable. Discover when and why a larger angle may be necessar
