PHYS 2001 Lecture : Lecture 3
Document Summary
Deals with the effects that forces have on motion. Our goal is to describe the motion of some object. To do this, we must be able to specify its location in space at all times! A vector which points from an object"s initial position to its final position. In this chapter, we will only consider 1 dimensional motion. Let"s look at the following example: o, a jogger s position relative to some fixed origin is x: at some later. At time t = t a jogger"s position relative to some fixed origin is x at some later. At time t = t time, t = t this time interval? f, her position relative to the origin is x: what is her displacement during t = t o t = t f origin x o. Her displacement, x, is the difference in her initial and final positions. X is pronounced delta x , or change in x .
