Talk:Kinetics (physics)

Removed this section: Biomechanics and Kinetics

I moved this section out of the article here, to the talk page. It belongs to an article about kinetics in sports, or of the human body -- after being cleaned up for tone.

One of the major components of Kinetics is analyzing ones Center of Pressure. Center of pressure (COP) is often tested using a force plate in a biomechanics lab. Many scientist don't always have access to these expensive and unique equipment. Force plates can be any from thousands to tens of thousands of dollars. Scientist and students today have turned to an alternative way, by using Nintendo Wii Balance Board system as a force plate. One study that is being conduct by graduate students at San Diego State University are looking at sway in athletes in a taped ankle compared to a braced ankle. The students expect their results to find that ankle bracing will reduce sway and decrease ankle instability and falls. Postural sway is the measurement of the time and distance a subject spends away from an ideal center of pressure. Measurement of a subject’s center of pressure has been used as a method of quantifying postural stability.Investigators have theorized that if ankle injuries cause differentiation and functional instability, a subject’s postural sway should be altered.Bracing has been known to provide cutaneous afferent feedback in maintaining postural control. The feedback follows the same neurological pathways in which the external ankle brace enhances the replication of the joint position. Although some may argue that braces have a negative impact on sport performance, the effectiveness of their mechanical stability make them of high priority and necessity. Due to the high incidence of ankle injury, the control of stability and body sway remain of most importance in reduction of injury and better quality of life.

I removed this section again, as it's clearly off-topic for this article (although it would make a very interesting addition to a sports physics article). In case it's helpful, here's the latest version of the removed text:

== Biomechanics and kinetics==

One of the major components of kinetics is analyzing one's center of pressure. Center of pressure (COP) is often tested using a force plate in a biomechanics lab. Many scientists don't always have access to these expensive and unique equipment. Force plates can be any from thousands to tens of thousands of dollars. Scientist and students today have turned to an alternative way, by using Nintendo Wii Balance Board system as a force plate. One 2014 San Diego State University study has shown a correlation of $r=0.99$ for the center of pressure measured using the Balance Board compared to a gold standard measure. The students expect their results to find that ankle bracing will reduce sway and decrease ankle instability and falls. Postural sway is the measurement of the time and distance a subject spends away from an ideal center of pressure. Measurement of a subject's center of pressure has been used as a method of quantifying postural stability. Investigators have theorized that if ankle injuries cause differentiation and functional instability, a subject's postural sway should be altered. Bracing has been known to provide cutaneous afferent feedback in maintaining postural control. The feedback follows the same neurological pathways in which the external ankle brace enhances the replication of the joint position.

Although some may argue that braces have a negative impact on sport performance, the effectiveness of their mechanical stability make them of high priority and necessity.

Please, let's discuss here before putting this text back.DrPippy (talk) 15:00, 28 November 2020 (UTC)

References

Should this article be deleted/redirect to Analytical dynamics?

As mentioned in the lede, the term kinetics in physics has largely been superseded by the term dynamics. Furthermore, the Biomechanics section does seem out of place (and I will remove it later today). This leaves a very short article about an essential concept in physics that is treated in far more depth in the Analytical dynamics article, which is the modern name for this concept. Is there a reason to keep this article around, or would it be better to delete it and have it redirect to the dynamics article? Personally I could go either way, but would probably prefer the redirect. DrPippy (talk) 14:53, 28 November 2020 (UTC)

I'll go ahead and make the move if there are no objections in the next 24 hours. DrPippy (talk) 15:16, 12 December 2020 (UTC)
