  1. Do not ping the Moderators, unless someone is breaking the rules.
  2. Do not ping the Helper Moderators, unless there is a conflict between helpers.
  3. Do not ping other members randomly for help.
  4. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  5. Wait patiently for a helper to come along.
  6. If the Helper has answered your question, remember to thank them with the Mathematics Ranks bot and close the thread with:

Feel free to nominate the person for helper of the week in #helper-nominations
If you're happy with the help you got here, and the server overall, you can contribute financially as well:

definite integration ?

#

but will I be able to use definite integration for example from 2 to 5
as he didn't put less than or egual ?

Other than that, yeah, just integrate. After all, the change in kinetic energy is just work done by the force.

limber seal
sullen sparrow
#

Yes.

limber seal
#

so therfore
change in potential energy = - work done?

#

right?

#

he didn't ask about it in that question

#

but for future questions it might help

sullen sparrow
#

Other than that, yes.

#

By definition, dW = F·dl.

limber seal
#

W is for work

sullen sparrow
#

Oh, sorry, didn't notice the potential energy.

#

Yeah, if we're talking about the potential energy, there will be a minus.

limber seal
#

noted

sullen sparrow
#

After all, since U + T = E = const, that means dU = -dT. Thus, dW = dT = -dU.

#

(assuming no dissipation of energy, of course)

Thanks sir

#

🫡

sullen sparrow
#

You're welcome!

#

Why "sir", though? 😅

limber seal
#

in my culture

#

Regardless of age just for showing respect

sullen sparrow
#

Oh. Hm, ok.
