A Moment in Boston History Boston‚ Bloody‚ Boston is a documentary that depicts actual events that happened in the year 1765. The history of when and whom the key players leading up to the Revolutionary War in Boston is the focus on this mini-series. As historians can focus on the true story of what happen in Boston‚ there is often times some misconceptions of what we can perceive as truth. Many documents and photographs were all truth telling to make this documentary as true as possible. Interviewing

ello Doc Al and others. I am progressing along with my on-line basic physics course. I completed a new module and have some assessment questions to answer. Please review and let me know the ones that are correct. Those that are wrong just a little clue as to where my thinking process went a stray. I will add my thought process to the ones that I missed telling how I came up with the answer that I did. Thanks for taking the time to assist me on some basic questions. 1. What is the rotational speed

any orientation. Although this orientation does not remain fixed‚ it changes in response to an external torque much less and in a different direction than it would without the large angular momentum associated with the disk’s high rate of spin and moment of inertia. The device’s orientation remains nearly fixed‚ regardless of the mounting platform’s motion‚ because mounting the device in a gimbal will minimizes the external torque. The examples of the application of gyroscope is in inertial navigation

I. Introduction Physics is the natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics was a part of natural philosophy along with chemistry‚ certain branches

Translational motion Translational motion is the aspect in which a body moves from a specific point to the next. This can be in terms of objects‚ molecules or atoms. This kind of motion normally takes place in a straight line for instance bullet which is fired by a gun. The object in motion does not change by turning on its axis for it travels in a straight line. Any slight change or rotation can cause the object to change direction in general making it not move toward the specified direction.

BALANCING OF ROTATING MACHINES The first thing to be explored to control vibrations is to try to alter the source so that it produces less vibration. This method may not always be feasible. Some examples of the sources of vibration that cannot be altered are earthquake excitation‚ atmospheric turbulence‚ road roughness‚ and engine combustion instability. On the other hand‚ certain sources such as unbalance in rotating or reciprocating machines can be altered to reduce the vibrations. This can
