PHYS 185: Physics

Explore the concept of capacitance and learn how to calculate potential difference, the impact of separation, and the work required for a parallel-plate air capacitor.

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.

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.

Discover the fascinating world of Slinky physics as we explore the speed of transverse waves when this iconic toy is stretched by a 2.0-N force. Dive into the science behind the Slinky's behavior!

Explore the physics behind calculating the velocity of pebbles thrown by Romeo to hit Juliet's window with only a horizontal component.

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
