## Unit 1: Constant Velocity Model (CVM)

Objectives of the unit:1. You should be able to determine the average velocity of an object in two ways:a. determining the slope of an x vs t graph.b. using the equation of the line from the x vs t graph2. You should be able to determine the displacement of an object in two ways:a. finding the area under a v vs t graph.b. using the equation of the area (or solve out the scientific equation from the x vs t graph)3. Given an x vs t graph, you should be able to:a. describe the motion of the object (starting position, direction of motion, velocity) b. draw the corresponding v vs t graphc. draw a motion map for the object (optional). d. determine the average velocity of the object (slope). e. write the mathematical model which describes the motion in y=mx + b format. 4. Given a v vs t graph, you should be able to:a. describe the motion of the object (direction of motion, how fast) b. draw the corresponding x vs t graphc. determine the displacement of the object (area under curve). d. draw a motion map for the object (optional). e. write a mathematical model to describe the motion. Terms and Definitions:Average Velocity = Slope of x-t graph = Change in Position= xf - xi Change in Time tf - ti Dx = change in position = xf - xi = displacement = area under v-t graph. Displacement is the straight line distance between the starting point and the ending point. Displacement also reports the direction of motion.Distance = total distance traveled along a path to get from the starting postition to the ending position. Think of this as an odometer or pedometer reading.Distance along path Average Speed = Change in TimeScalar = A Quantity that tells "how much" only i.e. speed, time, mass, odometer reading . . . Vector = A quantity that tells how much and which direction i.e. velocity, displacement, force . . .Qualitative = Conceptually correct, but not numerically preciseQuantitative = Numerically Accurate |
