I wondered about this question. According to me, there 2 ways you can look at it. A system can have energy, or a system is energy. Next to that, the idea of energy, the definition of energy seems a bit vague to me. There are so many types of energy, but what is it really? A system can have...

Hello, I am a high-school student, living in The Netherlands. Next year it is my time to study on an university. I was convinced to go to the University of Groningen to do the double bachelor in physics and math, however.. I am not so sure anymore after seeing the university of Utrecht. I was...

I have had a bit of calculus, yeah.

Hello, I am a high school student doing a project on pulsars and I would love to get into the deeper workings of a quantum electromagnetic field, but I am a bit lost. Since pulsars are neutron stars, who send out a beam of electromagnetic waves, I was quite curious about it's workings. So...

I have noticed doing a small experimental science project really helps! This year I have been working on building a rocket with two classmates, and we need to make a project at the end of our last year of high school, which really helps to go through certain material. But still, I feel better...

I live in The Netherlands. We don't really take classes, we have Physics through our entire high school. Lorentz force was covered the first time last year, which is the 5th year of high school.

Yes, that is true. Thank you for your reply!

Thank you for the recommendation! I will buy it asap, including the calculus book you mentioned.

Thank you so much for your reply!

Hi @PeroK , Thank you for your reply!

I am in the last year of my high-school with an aspiration to do a double-bachelor in Physics and Math. I am not sure if I am capable of doing so (I am not the smartest), but it is really one of my dreams to study both subjects, so I will try. However, sometimes I experience some difficulty in...

Hello, thank you for all your answers! I understand it better now and I was clearly wrong in my assumptions, so thank you for correcting me!

Knowing all the forces, would in the end tell you who is really moving, as it seems to me.

In trying to understand a bit of special relativity, I want to make sure if I understand it correctly, and I came up with the following question: "Imagine you would know all forces in the universe acting upon an object, doesn't that give away the only real existing frame of reference (imagining...

Since a phone is an object which can show three dimensions on a two dimensional screen, I wondered what a two dimensional being would see when they look at a smart phone or any other screen. So:What would a two dimensional being see, when they look at a smartphone?
