PHYS 170: Physics 2

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

Learn how to calculate total displacement when traveling west and south at different speeds and durations. Explore the direction and magnitude of your journey in this informative video.

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.

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.

Discover the magic of total internal reflection in this video! We explore how a ray of light refracts when traveling from glass into water. Find out the critical angle needed for total reflection, preventing any light from entering the water. Dive into the world of optics and refraction.
