Dynamic vs kinetic vs static in physics

[shushi_boi]

This is not a homework question, just a simple physics question which I decided to ask here. I held off from asking in the other general physics forum because I get accused of asking random questions that are insignificant. I really want to understand these terms and how they are compared in physics. I understand that dynamic is work done as intended and static is the opposite I think.

So why not do some of your own research? The Wikipedia articles on the three topics you mention define them well.

http://en.wikipedia.org/wiki/Kinematics

http://en.wikipedia.org/wiki/Dynamics_(mechanics )

http://en.wikipedia.org/wiki/Statics

PF is great for asking about specific details, it's not designed as a primary source of information.

I got this all from my textbook, in mechanics and systems, but I did not know that wikipedia was a reliable scientific source for scientific knowledge. I appreciate your response billy, thank you for posting!

I probably wouldn't cite it for anything, but I've never been lead astray via wikipedia. ~99.9% of their stuff is cited with scholarly or other respectable sources and clicking the little number after a statement will take you to the link for the info. I use it frequently when I want some quick fast info. That and hyperphysics, the only problem with hyper is sometimes I feel like they don't go into enough detail. I haven't run into that issue on wiki.

In physics, dynamic, kinetic, and static are all terms used to describe different types of motion or energy. Dynamic refers to the overall energy and motion of a system, while kinetic specifically refers to the energy of motion. Static, on the other hand, refers to a lack of motion or change in a system.

In terms of work, dynamic work is the total work done on a system, taking into account both kinetic and potential energy. Kinetic work specifically refers to the work done by the motion of an object, while static work refers to the work done when there is no motion or change in the system.

These terms are important in understanding the behavior of systems in physics, as they help us analyze and predict the motion and energy involved. For example, knowing the dynamic and kinetic energy of a moving object can help us calculate its speed and trajectory, while knowing the static energy of a stationary object can help us determine its potential energy.

It is also worth noting that these terms can also be used in other sciences, such as biology or economics, but their specific meanings may vary. In physics, however, they are commonly used to describe the motion and energy of systems. I hope this helps clarify the differences between dynamic, kinetic, and static in physics.
