## Introduction

This paper discusses the selected amateur YouTube video, “Rotational Speed,” found at the following link: https://www.youtube.com/watch?reload=9&v=URfqQ_IZBLo. This short video, created and uploaded by General_Assassin, seeks to explain how the earth revolves around the sun and demonstrates how to calculate the speed of rotation (“Rotational Speed”). It reveals that the earth’s speed of rotation is 390km/second with respect to the cosmic microwave background radiation (CBR). This paper uses this understanding to describe how physics is applicable to the information presented in the video.

## Main body

As mentioned, the ideas that the YouTube video describes and explains focus on rotational speed, echoing the information discussed in class on linear and rotational velocity. The formula for angular momentum or inertia of rotation is as follows:

The formula for an extremely small object in comparison with rotational speed is:

Using this information, the video’s creator goes on to describe how the speed of the earth is measured against the stellar background (“Rotational Speed”). The result is a solar day that has 24 hours.

## Conclusion

The field of physics is pertinent to this discussion as it describes the basic principles dictating the natural or physical world, including the calculation of momentum and velocity in a wide range of physical situations. The conservation of rotational velocity is a concept that resonates with the ideas discussed in class; it states that the angular momentum of a given system will remain constant when there is no external torque acting on it (“Rotational Speed”).

Physics is, therefore, applicable to the selected video because it can guide scholars to use algebra and other mathematical formulas to describe and analyze different natural occurrences, including the earth’s revolution and rotation and the behavior of the solar system.
