Green Devil Science - Big Idea 9 - Force, Motion, and Energy in Waves

Big Idea 8 - Force, Motion, and Energy in Waves

Learning Goals

To diagram the relationship among force, acceleration, velocity, and position in wave behavior
To analyze waves in terms of force, motion, velocity, position, and energy
To relate wave behavior to common occurrences

Aligning Wave Parameters - Intro Lab Part 1

The initial lab for this unit allows us to investigate the relationship among force, acceleration, velocity and position for a weight on a spring. These relationships are used to determine the formula set for this wave unit.

Mass on a Spring - Calculation vs Lab Measurement - Intro Lab Part 2

This lab procedure allows you to take the original intro lab situation and compare calculations to actual lab results. The lab requires you to change masses and springs in order to determine the changes in system parameters.

Purpose: To plot a wave form and determine wave parameters for human motion

Questions:

What is the typical time period for human walking?
What is the typical frequency for human walking?

Variables: (x) subject measured; (y) time period and frequency

Constants: Data collection method

Control: Frequency less than or equal to 2Hz

"If-Then-Due-To" Hypothesis: "If human walking is plotted as a waveform, then the event parameters should be able to be calculated due to the uniform nature of the wave form."

Internal Comparison: Classmates Data

External Comparison: Google "Typical Frequency For Human Walking"
