PPT-Lab 7: Two-Dimensional Collisions

University of Michigan Physics Department Mechanics and Sound Intro Labs TwoDimensional Collisions You have now seen the laws of conservation of momentum and energy in action in onedimensional collisions and you have begun to explore rotational motion Now it is time for you to apply these concepts to a twodimensional situation. Date, Section, Pages, etc.. Mr. Richter. Agenda. Today:. Warm Up. Review HW from 7.1. Practice Problems for 7.2. Intro to Collisions (7.3). Tomorrow . Conservation of Momentum Lab. Thursday: . Review HW from 7.2. Organized method of problem-solving . Used in chemistry, physics, engineering, and medicine. Communicates the path to scientists that follow your work. Records your own path for your future use. Dimensional Analysis. figures in . only two dimensions? . In this lesson. you will learn how to represent three-dimensional figures with nets . by analyzing their faces and bases.. . One-Dimensional. line. line. segment. Dimensional Analysis. In Chemistry and every-day life you will often need to express a measurement using a different unit than the one that was initially used. . To convert between units we can use . A.

Coefficient in terms of Green’s functions. Peter Andras. School of Computing and Mathematics. Keele University. p.andras@keele.ac.uk. Overview. High-dimensional functions and low-dimensional manifolds. Manifold mapping. Function approximation over low-dimensional projections. Inelastic vs. Elastic. Pg. 233 – 239. Pg. 240 - 248. Momentum vs. Energy. All interactions conserve momentum.. They do . not necessarily. conserve kinetic energy.. Obvious example: Explosions. Kinetic energy before is zero.. Statistics. “One out of every four accidents can be blamed on poor backing techniques”. - National Safety Council. …If only trucks would bend…. Statistics. The cost of “Property Damage Crash” (a typical backing up accident) is presently estimated at an average of $7,400 per event. Shyamnath Gollakota. Dina Katabi. The Hidden Terminals Problem.
