Document Summary
Physics 181 spring 2016 two-dimensional momentum 1. This experiment will analyze a collision of two pucks on an air track. Pendulum, our main goal is to see if momentum is conserved before and after a collision. However, the previous experiment provided an inelastic collision and considered one-dimensional momentum, and this experiment will provide an elastic collision and will consider two-dimensional momentum. We will need to be able to handle two-dimensional vector arithmetic. Many physical quantities can be described with just a number often treating as being independent of any particular spatial orientation; these are called a scalars. Scalars are represented mathematically with plain, not bolded characters. Scalars do not have any special diagraming standards outside of usually just planting a character representing a scalar in a spot convenient for identification purposes. Such as an object having mass , a reaction lasting time , or a room having temperature .
