General calculus required for AP/college physics problems?

Click For Summary

Discussion Overview

The discussion revolves around the calculus concepts necessary for understanding and solving physics problems, particularly in the context of preparing for AP or college-level physics. Participants explore the relevance of derivatives, integrals, limits, and infinite series in various physics applications.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant inquires about the most common calculus problems encountered in physics, suggesting derivatives, integrals, limits, and infinite series as potential topics.
  • Another participant notes that calculus is often first seen in kinematics, particularly in deriving position functions from constant acceleration, and mentions that calculus is used to calculate work done by varying forces and in potential energy calculations.
  • A participant expresses uncertainty about the frequency of calculus in introductory physics courses, stating that while it is used for derivations, many problems do not require calculus directly and often rely on free body diagrams and energy calculations.
  • One participant emphasizes the importance of mastering derivatives and integration techniques for success in a first semester physics course, suggesting that understanding kinematic equations and their derivations is beneficial.
  • Another participant agrees, stating that differentiation and integration are fundamental skills in calculus, akin to basic arithmetic operations.

Areas of Agreement / Disagreement

Participants generally agree on the importance of derivatives and integrals in physics, particularly in kinematics and problem derivation. However, there is some uncertainty regarding the extent to which calculus is applied in introductory physics courses, indicating that multiple views on its necessity and application exist.

Contextual Notes

Some participants highlight that while calculus is important for derivations, many introductory problems may not explicitly involve calculus, suggesting a potential limitation in understanding its application in practical scenarios.

I am supposed to take calculus next school year but I want to do some physics work over the summer. Can anyone provide me the the most common calculus problems in physics? I was thinking that derrivatives, integrals, limits, and infinite series would be the main ones but I am likely wrong.

Typically the first bit of calculus one sees in physics is in kinematics. Namely, the question of how to find a position function given a constant acceleration, knowing that acceleration is the second derivative of the displacement (with the velocity being the second derivative). After that, you can use calculus to find the work done by a varying force, it can be used in potential energy calculations (particularly when dealing with Newtonian gravitation). But I'm not so sure calculus is used that often in an introductory course in physics. It is used to prove certain things or to derive equations, but students typically don't see that many problems actually involving calculus. There are a lot of free body diagrams and energy calculations, but calculus only shows up in the less-than-ideal problems.

An example of its use to derive something is, for example, the position function given a constant acceleration. Given \frac{d^2 s}{dt^2} = a and the initial values s(0) = s_0 and s'(0) = v(0) = v_0, we can integrate twice to get s = \frac{1}{2}at^2 + v_0 t + s_0 But this is merely to derive the formula, and unless you really hate memorizing formulas, it's not typically done more than once.

Learn how to take a derivative inside and out.
Beyond basic derivatives and integration techniques you won't need much in a first semester physics course. It is of course, to your advantage to get a head and I suggest learning intimately the kinematic equations posted earlier and how they are derived. How the derivative of the position function is the velocity and the derivative of the velocity function is acceleration.
 
RJLiberator Agree
Firest you have to start from derivation and integration, then move to more complex problems

Yes. 100% agreed. To me, differentiation and integration is like the 'addition and subtraction' of calculus.
