PHYC 215: Human Physiology

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

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.

Dive into the world of projectile motion as we calculate the horizontal and vertical distances a launched projectile covers. Explore the impact of angle and speed on the trajectory, all explained in this engaging video.

Discover how to calculate rope tension with an object hanging in the center. Understand the relationship between the sag, the weight of the object, and the tension. Convert the result into kilonewtons for easy reference.

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.

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.
