PHYS 101: Essentials of Physics

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.

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

Discover how energy conservation principles determine the velocity of a bouncing ball. Relate the ball's height and its potential and kinetic energies. Understand the velocity change upon impact and rebound.

Dive into the thrilling world of physics and surfing as we explore the angle of inclination of a wave's face. Discover how a surfer accelerates down a wave with an acceleration of 3.25 m/s² while ignoring friction. Join us for an engaging and educational explanation of this exciting phenomenon.

Discover the dynamics of a commercial jet takeoff in this video! We explore tire rotation speed, centripetal acceleration, and a bacterium's grip on the rim. Dive into physics and microscopic forces, all while considering weight ratios.

Explore the fascinating optical phenomena involving a cat, a converging lens, and the creation of virtual and real images.
