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.
Hotel Peephole Lens: Achieving a 180-Degree View Through Refraction
Want To Learn More? To watch the entire video and ALL of the videos in the series:
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.
Lunar Lander Descent: Initial and Final Velocities
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Join us on an exciting lunar adventure as we explore the descent of a lunar lander towards the moon's surface. We'll unravel the physics behind its journey using the equation y(t) = b - ct + dt^2, and answer questions about the lander's initial and final velocities. Get ready to explore the dynamics of space exploration and lunar landings in this informative video!
