PHY221
Linear Dynamics

_______________
 

Overview
Title Linear Dynamics

Purpose
In the previous lessons you have learned basic tools of vector addition (subtraction)
and the skills needed to solve motion problems in two and three dimensions
(called kinematics). This module will introduce you to the source of motion,
interactions called forces.

Prerequisites
o Successful completeion of Kinematics competancy)

_______________
 

Target Learning Outcomes
 

Target Competency
3. Analyze the linear dynamics 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 dynamics of physical problems
o by successfully completing online quiz (at least 70%)
o by using a scientific calculator
o by using text and notes
o without a "partner"
o by successfully completing in-class assessment (conditions with assessment)


Your performance will be successful when:
o you distinguish between equilibrium and accelerated motion
o you apply Newton's laws to situations where acceleration is non-zero
o you apply the five kinematic equations and Newton's 2nd law to physical problems
o you distinguish between and explain Newton's three laws of motion
o you distinguish between mass and weight
o you distinguish between static, sliding, and rolling friction
o you perform unit analysis on algebraic relationships
o you draw and label interaction (free-body) diagrams for a system of objects
o you apply Newton's laws to situations where acceleration is non-zero
o you apply Newton's laws to situations where acceleration is zero
o you apply the concept of friction
o you apply Newton's second law to a particle moving in circular motion

Learning Objectives
This learning plan addresses the following learning objectives to help you master the competency:
a. Describe with examples Newton's law of inertia (first law)

c. Describe with examples Newton's law of reaction (third law)
d. Define friction
e. Write Newton's second law, friction equations, and the kinematic equations
f. Write the characteristics of static, sliding, and rolling friction
g. Define mass, weight, and gravity
h. Create and label interaction (free-body) diagrams for objects on horizontal or inclined surfaces
i. Create and label interaction diagrams for objects suspended from two or more cords
j. Create and label interaction diagrams for objects suspended or supported by a horizontal beam

l. define centipetal acceleration
m. define uniform circular motion
n. define tangential acceleration
o. define radial acceleration
