PHYS 202: Physics II

Discover how to optimize the launch tube acceleration to achieve the maximum height and earn the most points in your laboratory experiment.

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 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.

Explore the fascinating comparison between the acceleration of a motorcycle going from 80 km/h to 90 km/h and a bicycle accelerating from rest to 10 km/h in the same time frame.

In this educational video, we dive into the concept of volume and its units. We explore the correct units for measuring volume and discuss the common misconception that a cylinder's volume is given by ?r^3h. Join us for a comprehensive explanation of the fundamentals of volume measurement and understand why the given formula doesn't hold.
