AI Thread Summary
Frustration with physics often stems from the misconception that it is merely an extension of math, leading many students to struggle when faced with its conceptual challenges. Success in physics requires a deeper understanding and physical intuition, rather than just relying on formulas. Developing this intuition involves careful attention, critical thinking, and extensive practice with sample problems. Students are encouraged to focus on genuinely learning the material instead of solely aiming for high grades. Emphasizing comprehension over memorization can lead to both academic success and a more fulfilling learning experience.

Hello all,

I recently discovered these forums and I am amazed at how much endless info you have in this joint

This isn't a typical "Help me solve this kinetic energy problem" question, but rather my overall frustration with the subject.

I've always excelled in Math, it has been my best subject since I was a kid, and I've received As in the subject from grade 1 up to this day in college. Up until the point when I took physics in High School, my mind had been molded into thinking that physics was yet just another math course. I was wrong. In the AP Physics class, I'd slack a bit, assuming it would all be cake. Afterall, I never had to do much studying in math. I was wrong again--I finished the semester with a C+. Then when I actually did buckle down and started working, I found myself annoyed not being able to answer all the answers. Sure, I could answer the easy ones, but not the dreaded "RED" questions. I finished the semester with a B+. Sigh

I'm now an undergrad majoring in Math and Economics. Unfortunately( or fortunately) I have to take physics again. If any class, this one has the potential to hurt my perfect GPA. Perfectionist, you may say, but that's how I go about doing things.

Do I take the wrong approach? Is it better to learn this subject for the sake of learning it, as opposed to getting a high grade?

Or maybe I'm too systematic and rely too much on formulas rather than understanding the concept. I don't know

Any feedback would be appreciated. Thanks

The most common mistake made my beginning physics students is to assume it's just easy math.

It's quite true that the math is usually pretty easy, and it's not what makes physics challenging. To do well in physics, you need to have a deeper understanding of exactly what you're doing when you apply a formula. You need to have physical intuition, and already have the form of the answer in mind before you even put your pencil to the paper. If you look at a problem, and have absolutely no idea what the answer will probably be, you will not do well in physics.

So how do you develop physical intuition? By paying careful attention, thinking before you leap, and doing lots of sample problems. Practice!

Relying on formulas is like putting crutches on your brain. It is much better for you to stop worrying about the grades and the memorization and focus on really understanding the subject. Anyone can take and pass a class, but it takes some real gusto to actually learn and understand the material.

If you really are the "perfectionist" you claim to be, practice and develop an intuition for physical situations and you will be setting yourself up for the grade and for future success...
Boy that sounded after-school-specialish...

Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
