Planetary orbits are elliptical because gravitational interaction over time changes the delicate balance of mass, velocity and distance from the star which otherwise keeps planetary orbit circular. For a very long time, from Ptolemy to...

In this video, we focus on motion graph problems as part of the AP Physics 1 exam review. Join me as we dive into understanding position, velocity, and acceleration graphs and their relationships. This video is part of my comprehensive...

In this video, we continue our AP Physics 1 review by diving into kinematics and projectile motion. In this lesson, we walk through several multiple-choice problems related to projectile motion, which are similar to what you can expect...
