## Simple pendulum period depends on length, amplitude, gravity

Consider an ideal pendulum consisting of a “bob” of mass m hanging from a light (massless) string of length L. The pendulum swings back and forth in simple harmonic motion (SHM). You may assume that the oscillations are small, so that the motion is “ideal” SHM. Which of the following statements are true? 1. If […]

## Work, Power and Force.

Please do not put your response in a .pdf format, but Word documents are okay. Thanks! (A) A sled of mass m is being pulled horizontally by a constant horizontal force of magnitude F. The coefficient of kinetic friction is mu_k. During time interval t, the sled moves a distance s, starting from rest. Find […]

## Geography

Research and share a geography-related current event found in the popular media (print newspapers like the Washington Post, magazines, and/or online websites such as National Geographic or Science Daily). News stories with geography-related content can include anything related to weather (hurricanes, tornadoes, droughts, record snowfalls or temperature, etc), natural disasters (earthquakes, volcanic eruptions, tsunamis, etc), […]

## Wavelength And The Wave Equation

1. What is the period of a wave (in seconds) that has a velocity of 1 km/s and a wavelength of 5 meters? (Answer must be number only-no units or exponents)2. What is the frequency of that wave in Hz? (Answer must be just a number – no units.) 3. What is the wavelength in […]

## Using The Scientific Method In Your Life

Conduct your own physical experiment using the scientific method. Research the scientific method and give a 1-2 page written description of each step. You will then document your process with photos and/or video. Results will also be shared by uploading such media (or the links) of your process to the discussion board in this module. […]
