1 PHYS-1000: Chapter 3 - Linear Motion Why : The question, “how does something move?” was the driving force behind the development of physics. Examples : Driving a car along a highway, dropping a ball, bowling Types of Linear Motion We are going to consider two types of linear motion (motion of objects in straight lines) problems: Horizontal Motion At constant speed At constant acceleration Vertical Motion At constant acceleration (near the Earth’s surface) Units and Symbols Throughout this class, we will use the Metric System or MKS units M - meters (length) K - kilogram (mass) S - seconds (time) C - coulomb (charge) Most other units we will use will be constructed from combinations of these units. Example: Force (N - newton), 1 N = 1 kg-m/s 2

2 Physics and math ( algebra!! ) Was I really supposed to remember that? We have to use some algebra to solve problems. Mostly, we will have to rearrange and solve a few equations. If you have problems - SEE ME IMMEDIATELY!! Some terminology Position, x - describes location of an object Symbols: x - position, d - distance, t - time d = (x 2 - x 1 ) Units: m (meters) Velocity, v - a change in position over time v = d/t = (x 2 - x 1 ) / t d = v*t Units: m/s Acceleration, a - a change in velocity
