What have you found so far? If you type that into Google, one of the resulting category tabs will be "videos"... :smile:

I would like to find plasma ball relationships with atomic physics.

OK, then proceed as suggested by @berkeman and then check out the search results one by one until you find the videos that match what your are looking for.

I think you may have suffered from the fact that the term Plasma is taken by search engines to imply you want to buy something that uses plasma. (That's what they make their money with.) You need to get past their defences.

You need to choose a suitable extra term if you want some Physics content. I tried Low pressure plasma formation" and that got me past the sales section into things that you may want. Web searching is all about asking the right question and that 's a skill that takes time and determination to acquire.

Sorry if that sounds smug but it's true. Think of it as an adventure game where you have to ask the dragon the right question before you get to the gold. Good luck.

No more from the OP.
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
