PHYS 111: Introductory General Physics

Join us for a dramatic river rescue mission! In this video, we solve the problem of how a rescue team can reach a child in danger of drowning in a fast-flowing river. We calculate the angle from the shore for their pilot to approach the child directly, considering the river's current and the boat's speed. Explore the principles of vector addition and save lives!

Explore the world of high-performance sports cars and learn how to calculate their average acceleration when accelerating and coming to a stop.

Uncover the secrets of watch crystals in this video! We convert the frequency of a quartz crystal used in electric watches into its period. Join us to explore the principles of timekeeping and crystal oscillations.

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.

Unlock the secrets of calculating electric charge using Coulomb's Law and discover the fascinating world of electrostatic forces. Learn how to determine the charge on two spheres, spaced 20.0 cm apart, and understand the role of elementary particles in this physics tutorial.
