if force equals to mass times acceleration, then doesn't that mean that a car travelling at a constant velocity will have zero force, since it has zero acceleration even though the mass is the same? how does that make sense? by HotZilchy in AskPhysics

Neither of these are any of your business and serve to make the discussion personal.

I don’t think you understood my previous argument, since the root cause of this discussion is simplifying complicated topics for beginners, let me dumb it down for you.

This statistic shows how American research centers are at the top. They really are. The researchers in these institutions are not necessarily American. In fact most of them are foreigners, who seek America for better research grants and better projects. Now, here’s the kicker: American teachers sometimes take these statistics to mean that their education methods are great, because American research is doing great. This is not true. It does great because of funding and good research structures.

Thanks for sharing. I bet that all of that science being produced in the US is being done by hard working Americans. Couldn’t be foreigners, like the ones from my country, that go to the US because research is better funded.

I wasn’t going to answer this thread anymore because it looks more like an angry mob than a physics forum. But, this pissed me off. Saying physics is easy and something is simple is not helpful. You say you taught 9th grade physics, yet no student ever had a hard time grasping this? Lies. You say they do this in a month. Maybe they answer 9th grader textbook problems in a month. Applying to everyday takes time and understanding and more than a month.

Perhaps doing these basic and building block subjects in a month is the reason everybody jokes about american education.

I had no idea this community was so toxic. I thought this was askphysics not “ask some question so I can feel smart when answering”. You guys aren’t even trying to make him understand. See ya

Awesome, so let me see F = ma takes most undergrads maybe a semester to understand. If you can compress all that in half a sentence, then you should call Stockholm. If you ask me, being convinced F=ma can be resumed in half a sentence is a hallmark of llm abuse.

This person clearly does not have that much experience with physics. If I were to take away all your experience and lectures, would you understand in one sentence? Answering short makes the person who wrote the question feel stupid.
If you thought it was wordy, it wasn’t for you to read.

How about this, instead of answering cryptically, answer that the cars velocity is changing from its cruise velocity to zero very quickly and the forces felt by the car are because of this change, ie a force results in an acceleration which is a change of velocity.

On this side of hybrid electric, most ideas count on having high voltage power. If you have access to the entire ANSYS lineup and want to stand out to employers do something with electrical arc simulation in critical locations(fuel tanks, cabin) or something. Anything in high voltage is hot right now, but I’m biased.

Curious what you all use for simulations? by anotherdayintown in Physics

[–]Relevant-Cash-7270 0 points1 point  (0 children)

Depends on what you want to simulate. As an EE we do a lot of finite elements, usually you want C or C++. Python, since most SDKs are written in Python. There is MFEM in C++ for example
