Question

@Jemurray3

Work problems.

Answer 1

While studying, I noticed that if I used \[P = F V\]
If the force is prepandicular to the velocity hat means work is = zero?

Answer 2

While studying I noticed that some cases the work = 0.
If I used the work-theorem to calculate the net work it might equal to zero.

Answer 3

Yes, that's true.

Answer 4

Ow I remembered that, in order for work to be done the force has to be parallel to the displacement. For some reason, I forgot a lot of information, and I re-studied a lot lately.
But its wonderful how the law of conservation is used to explain the work done in any closed system, or how you can even use the laws for other vectors that needs to be found at certain points.

Really interesting, I knew C.O.E but never looked at the blue prints to the masterpiece.

Answer 5

I'm don't know what you mean by some of that, but you're far from the blueprints....... someday. It's more elegant than you can imagine right now.

Answer 6

Well, all I can say for now! I started to remember a lot of things that I seem to have forgotten.
And I'm looking at the blueprints of C.O.E right now, but need to understand and use them.

Answer 7

What do you mean by looking at the blueprints of conservation of energy?

Answer 8

Thats a metaphorical statement.
I ment that... Now instead of just knowing the exterior of the idea.(PE + KE)
I know more of the interior, and looking at all the blueprints(structures,methods,ideas, examples) gives me more understanding.

lol.

Answer 9

I know it was a metaphor, I was just wondering what you're looking at now.

Answer 10

Ow I'm looking at how you can apply the laws of conservation in multiple examples.
Understanding more about "energy" and "work" and the forms of "energy".
Also looking at Thermodynamics.
