Instead of just being handed the kinematic equations, calculus allows you to understand where they came from, and even extend it to nonuniform acceleration.

Depends on the level of the course as well. I don't remember using much calculus in high school mechanics courses. But calculus was an integral part of almost all undergraduate physics courses.

So what you're saying is that I can't truly understand what I'm doing without calculus?

More or less, after all Newton developed calculus to explain the laws of motions. And if you intend to study more physics then calculus is almost indispensable.So what you're saying is that I can't truly understand what I'm doing without calculus?

There are many things you will take away from non-calculus physics. For example, you say you're studying statics now...well, you're learning how to draw a force diagram. That's very useful in calc-based physics.

I wouldn't think of high-school level physics it as wasted time, if that's what you're wondering.

Maximizing functions is another useful thing you can do with calculus that showed up in a good amount of problems in my physics classes.

Now in my physics II class, I use alot more calculus even if they all solve very easily, it would be impossible to memorize all the different equations for all the different little situations.

You can actually understand stuff without the maths behind them. Maths make it easy to see where the folks are coming from..

When I took HS algebra-based physics, my teacher told the class that you couldn't solve x(t)=at

She also thought the density of water was 1 kg/m^3 and that work only occurred if a force was applied in the x direction...it was miserable.

Or you can learn physics.

One of these requires calculus, the other does not.

I learned infinitely more in physics with calculus. Equations also give you insight into the physics. Just seeing A=BC 100 times over doesn't say much. In my opinion physics is best learnt in the language it was derived in. What you're getting are the left overs not the main course.

There are actually quite a few things you can do in mechanics with no calculus at all: statics (hydrostatics too), uniform motion, Newton's laws, the basics of energy, momentum etc., so no, I would not say mechanics without calculus is useless. And if you know calculus but not the proofs of calculus, then it is not much better than not knowing calculus, isn't it? The only thing that matters is the idea of "limiting" or approximating something in many small steps, and then saying that in the limit everything works out. Archimedes knew this long before calculus was invented. This is the idea behind many calculus proofs anyway, and exactly why calculus is so important to physics. In fact, if you know calculus but not its proofs, then it seems it is sometimes used as a magic tool where results pop out, with not much intuition for WHY things should be so, and it is usually the idea of limiting that is obscured. Calculus allows you to do a lot more, but it doesn't necesarily add insight.

I know I'm blabbing and not saying anything precise, sorry...

Excellent insight! I can't wait to start calculus then :)
