In this video David quickly reviews the momentum and impulse topics on the AP Physics 1 exam and solves an example problem for each concept. Created by David SantoPietro.
Investigate collisions on an air hockey table. Set up your own experiments: vary the number of discs, masses and initial conditions. Is momentum conserved? Is kinetic energy conserved? Vary the elasticity and see what happens.
This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"In 2014, Major League Baseball, in conjunction with the MLB Players’ Association, instituted a controversial rule change designed to prevent home-plate collisions. Rule 7.13 states that a runner attempting to score may not deviate from his direct path to the plate to initiate contact with the catcher. Similarly, the catcher cannot block the runner’s path in his bid to score. Some players and managers were initially concerned that the rule would alter the nature of the game. But data show that in the higher-stakes matter of player safety, Rule 7.13 is a clear win. Using the MLB Health and Injury Tracking System, a database recording all injuries to players in the major and minor leagues, researchers from MLB and the MLB Players Association looked at how the 2014 rule change has altered the profile of player injuries. Specifically, they compared the incidence of some traumatic brain injuries, or TBIs, in the seasons prior to and after the change..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.
David explains what it means for a collision to be elastic or inelastic. Created by David SantoPietro.
These Interactive Physics Demonstrations were developed by MAJ James Bowen, MAJ Cathleen Barker, MAJ Andrew Wilhelm, and others at the United States Military Academy for their University Physics course. Each activity is presented as a worksheet, which guides students through an experimental or observational process with questions.
This class is an introduction to classical mechanics for students who are comfortable with calculus. The main topics are: Vectors, Kinematics, Forces, Motion, Momentum, Energy, Angular Motion, Angular Momentum, Gravity, Planetary Motion, Moving Frames, and the Motion of Rigid Bodies.
Physics I is a first-year physics course which introduces students to classical mechanics. This course has a hands-on focus, and approaches mechanics through take-home experiments. Topics include: kinematics, Newton's laws of motion, universal gravitation, statics, conservation laws, energy, work, momentum, and special relativity.
These lecture videos were made during the pandemic when most classes went online. They cover most of Physics-1, and a few chapters of physics-2. Subject: Physics Level: Community CollegeMaterial Type: LectureAuthor: Khalid BukhariDate Added: 2/19/2024
