This worked every time but once. The pane of glass remained perfectly intact but popped from its case.

@wrathcyber
@wrathcyber Жыл бұрын
If you're interested in the proof: Energy is conserved in this system.. Therefore, E initial = E final. Using this, we can use the formula for kinetic translational energy K = 0.5(m)(v)^2 and set it equal to mgH (gravitational potential formula). H is the initial starting height. You can simplify this by canceling out m and g constants from both aides since they do not change. We are left with H = 0.5(v)^2 Therefore, v(velocity)will change based on the height but will never exceed the total output of gravitational potential energy.

Explain to me how you could do anything like this when learning 95% of the topics you learn in a physics degree. You need to learn from a textbook. It is the best way to learn. Most of the time, it is the only way to learn. Don't believe that 'you just forget it after the exam' bs either - it's not about your capacity to remember, it's about your capacity to have been able to learn it.

@@Michael-mh2tw I'm unsure what you're trying to say. Are you suggesting that lectures don't add anything? In my college classes, the quality and coherence of the professor was instrumental to my understanding of the material. Reading the textbook is one way to learn, but even though I like reading, math and physics textbooks are very dry, and my eyes tend to glaze over. It doesn't make sense to me unless someone walks me through it, preferably while drawing diagrams or graphs on a whiteboard. Taking notes is crucial. I was homeschooled in high school, and math was one subject where I fell behind, since I had no teacher and was just attempting to absorb information from textbooks. At community college I took an algebra course online where the professor was barely even existent, and I got a B (I had to watch Khan Academy videos on the side to pass). When I went to a university, my Trigonometry and Calculus teachers were very good, and I got an A in both classes. My physics professor was hard to understand, and I got a B (I really should have gotten a C, but he was a lenient grader).

We had a physics professor who got around with the use of the old style crutches that have cuffs that clip to your wrists. He once did a demonstration on inertia where he carefully climbed onto a wheeled platform and then by shifting his body weight, could make the platform move. Problem: The floor in the lecture hall was not level and he ended up rolling out the door and into the hallway. I suspect he knew this would happen and did it for comedic effect, but it was still hilarious.

​@@tam6493 I mostly agree with you, except for one little detail. When I was in college, I met quite a few of really useless professors. They talk, they show slides, they give homework. However, I knew this stuff will not get me ready for the exam, because what they teach in class is only 10% of the whole material. You can bombard them with emails, catch before the class, book the office hours, but it will work not always. If the professor is _determined_ not to work, he will continue feed you single-worded answers, like "it's all online", or "ask your peers", etc. I skipped classes deliberately when I knew I am not advancing anywhere by attending them. Instead of focusing on something I can read myself faster, I will better sleep or cover more stuff in a book. In most cases, my grades went up because of skipping a class. You don't pay only for the class. You pay for credits, exams, homework, and finally, the diploma itself. _But_ _that's_ _a_ _completely_ _different_ _story._

That "you paid to be here" argument doesn't work tbh. If you can get the grade and knowledge you want while not showing up, you're not wasting money. I know some professors want to think their class is the most important thing in the universe, but many courses don't require much effort to do well in. It's not the student's fault if a class isn't particularly demanding. I even think attendance policies are dumb(in university). If a student can do well in a class while only showing up occasionally, why should they be punished?

Nice of him to show this kind of visual example. He is a smart physics teacher and knows it is not as dangerous like he pretends because when the object reaches his chin, it has almost no kinetic energy to cause serious damage even if he had pushed it a “bit”. The object has most kinetic energy at its bottom most point in the swing (not towards top most point)
