PHYS 221: Physics 1

Unlock the secrets of battery performance in this video! We calculate the terminal voltage for a battery with internal resistance, connected in series with resistors of different values. Explore the effects of resistance on voltage in electrical circuits.

In this enlightening video, we unravel the mysteries of electric charges and forces. Discover the fascinating concept of how the separation between two identical tiny spheres, each carrying the same electric charge, influences the force they exert on each other. Will the force double, become one-quarter as large, or remain unchanged? Join us to explore the intriguing world of electrostatics and the principles that govern electric interactions.

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.

Explore the physics of a light-rail commuter train's motion. Understand how to calculate times for acceleration and deceleration using the equations of motion. Dive into the concept of emergency deceleration and its implications.

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.

Analyze the physics of a falling squirrel, calculating its velocity upon hitting the ground and the deceleration due to limb bending.
