PHY221
Kinematics

_______________
 

Purpose
Historically man has been fascinated with things, from clouds to baseballs, that move.
Determining how fast things are traveling and getting them to end up where we want
them to has been one of man's challenges. In this module you will learn how to
determine these things for special cases. You will also begin learning skills that will
help the next units of study

Prerequisites
o Successful completion of the measurement competency

_______________
 

Target Learning Outcomes
 

Target Competency
2. Analyze the kinematics of physical problems
Linked Core Abilities
A. demonstrate ability to think critically
B. solve problems
C. demonstrate effective written communication
D. apply scientific concepts
E. demonstrate essential computer skills

Performance Standards
You will demonstrate your competence:
o by analyzing the kinematics of physical problems
o by using text and notes
o by using a scientific calculator
o without a "partner"
o by successfully completing online quiz (at least 70%)
o by successfully completing in-class assessments (conditions with appropriate assessments)


Your performance will be successful when:
o you apply vector mathematics to one, two, and three dimensional motion problems
o you explain average velocity, acceleration, and speed
o you distinguish between average and instantaneous values of velocity, acceleration, and speed
o you sketch and recognize graphs for constant/non-constant acceleration
o you apply the five equations for uniformely accelerated motion to solve physical problems
o you perform unit analysis on solutions to problems
o you draw and label models for physical situations (problems)

Learning Objectives
This learning plan addresses the following learning objectives to help you master the competency:
a. define position vector

k. draw and label the temporal model of a physical system (kinematic)
l. write the mathematical model for a physical kinematic system (five equations for uniformly accelerated motion)
m. make appropriate substitutions into the five equations for uniformly accelerated motion
n. solve five equations (of motion) "simultaneously"
o. apply unit analysis in solutions
p. from R(t) calculate v(t)
q. from R(t) calculate a(t)
r. from a(t) calculate v(t) or R(t)
