Agreed Funny looking back on that post now having a background in calculus differential equations and linear algebra

If you son is not interested in pursuing a career in physics or math related than there is no need to worry as long as he understands what he is learning through the schooling system.

Welcome to PF.

Welcome to PF, just go to the home page https://www.physicsforums.com/ and scroll through and find the category your question goes under

I agree why drop A-Level physics as a requirement which would be a huge necessity for going into a field like engineering, maybe if they aren't smart enough to go through A-Level physics they shouldn't be going into engineering.

Do you have the free version of AVG if so I suggest purchasing nortons or symnantec. Do any of these appear as well? -CPU is always running at high processing -Programs don't function properly like they use to -There files on your computer you don't remember downloading (or files are missing)...

well for the wall to sustain the force exerted from the ball without breaking it has to exert some force back into the ball making it go into the other direction

That's pretty funny, they do look quite similar.

The ball will always have to some what bounce back unless the ball went through the wall.

you need to use uniformly accelerated motion equations instead. If you don't know what these are I suggest reading through the beginning of your textbook. the equations you will need are position equation and velocity equation.

The United States has an abundance of Universities for physics and I'm by the looks of it an abundance of research jobs. Here's a list of Universities that are ranked high in physics https://www.usnews.com/education/best-global-universities/physics, I'd suggest looking over their websites and...

I could possibly help what country are you/have you moved to?

In the past I've always felt an anxiety when speaking to large amounts of people but I don't think to your extent when the time passed and I had talked in front of hundreds of people it started to go away, I always feel stressed about having to present something I don't like or I'm not familiar...

"If you think you understand quantum mechanics, you don't understand quantum mechanics" Personally I started learning some quantum physics but decided to stop and cement my understanding of other physics and learn the mathematical side of it a little more before fully trying to learn it myself...

Hello, I found some interest in this and decided to try and find a mathematical solution. First using the range and an estimate of the angle I roughly calculated what the initial velocity would have been, then taking that and finding the mass of the picture frame which I see as quite accurate...
