Title: Displacement and Pressure
Category: Sound Waves
Summary: This LO will focus on a comparison between displacement and change in pressure in sound waves. It is a screen recording of a presentation along with some helpful tips through narration. I enjoyed making it, and I hope it can help clear things up if anyone is confused. Enjoy!
Title: Physics 101 Learning Object Week 6 Harmonic Wave
Category: Harmonic Waves
Summary: Use the wave speed relationship equations in harmonic waves and apply it to find the frequency of whale calls in a power point word problem.
Category: Harmonic Waves
Summary: A PowerPoint summary of the properties of harmonic waves as well as the major equations involved in a 2D and 3D plot. A multiple choice question and word problem show how the equations are applied to harmonic waves.
Title: Investigation of Phase and Phase Difference
Category: Phase and Phase Difference
Summary: This learning object investigates the concept of phase and phase difference. Two new formulas related to position difference and wavelength are derived. Prezi is used to deliver the whole presentation, which includes basic concept and a multi-part word problem with detailed solution.

Title: Position and Time Plots
Category: Position Time Plots
Summary: In this learning object I focused on extracting wave characteristics such as amplitude, wavelength, and frequency from position and time plots.This learning object also illustrates how to use these variables in relationships we know to find wave speed and angular frequency.
Title: Identifying Phase and Phase Difference
Category: Phase and Phase Difference
Summary: After doing this week’s pre-reading assignment and tutorial, me and my friends were confused about what exactly phase was. This LO addresses the concepts of phase and phase difference through a PowerPoint presentation.
Category: Damped Oscillations
Summary: My learning object gives an overview of what damping is and the equations for damped oscillations. It breaks the equation down into parts and then there is a sample question and a solution at the end. I chose to make a powerpoint for my LO.
Category: Simple Pendulum
Summary: Overview of the basics of a simple pendulum. Explores relations between mass, length of string, period, and energy. Some problems and solutions to these problems are provided at the end of the document to confirm your understandings.
Category: Simple Pendulum
Summary: This Learning Object addresses two questions that have been found on a physics midterm. The first one explains the concept of velocity in the simple pendulum The second looks at the law of conservation of energy associated with the simple pendulum. I chose to use Prezzi for this Learning Object to show diagrams and calculations in a simple orderly manner.
