Vibrational Motion


A Concept-Builder is an interactive questioning module that presents learners with carefully crafted questions that target various aspects of a concept. Each Concept Builder focuses the learner's attention upon a discrete learning outcome. Questions target that outcome from a variety of angles using multiple difficulty levels or varying activities. The following Concept Builders target concepts in Vibrations and Waves.



Period and Frequency of a Pendulum
 
Learning Goal: To distinguish between the frequency and the period of a pendulum and to identify the variables that affect their values.



Pendulum Motion:  Velocity and Force Analysis
 
Learning Goal: To relate magnitude and direction information about the velocity of and the forces upon a pendulum bob to the location of the bob along its trajectory.



Energy Analysis of a Pendulum
 
Learning Goal: To use words, energy bar charts, and numbers to identify how the kinetic energy, potential energy, and total mechanical energy change as a pendulum bob swings back and forth.



Period and Frequency of a Mass on a Spring
 
Learning Goal: To distinguish between the frequency and the period of a vibrating mass on a spring and to identify the variables that affect their values.



Vibrating Mass on a Spring: Velocity and Force
 
Learning Goal: TBD
