Yeah lol, is it easy?

I just looked at the syllabus for the premlin course. It has things like courses which are named The World Communicates, Electrical Energy in the Home, Moving about and cosmic machine. Is that what you learn now?

Yes, thats what I meant about the mountain:) Thanks heaps. I learnt a lot today.

Because Physics is not like other sciences. Chemistry and Biology are a lot about memorizing, I am interested in Physics, and plus my school had very limited options, and there wasn't really a whole lot I was interested in.

For example, pretend this is a mountain. A _______________________________________ B Walking the whole thing is 120m, and I finished my journey on Point B and didn't move after that, so my displacement is 120m, right?

Point B. I landed on Point B which is the point where I finished my journey. I didn't go back to my starting point. I landed at the end of my journey. A straight line.

I am not looking at it from the house to the 100m distance, I'm looking at it from 100m distance to my house, so it would be west, wouldn't it? Are you meant to look at it the other way around?

Thanks a lot. I hope I can do well in Physics. It would mean so much to me because I have always hated science; struggled to get a hold of the concepts, and most of the time, I have been getting a D on my report. I'm doing Legal Studies, 2 Unit Maths, Standard English, Society and Culture, and...

No, I didn't go back to my starting point because we are talking about a straight line here. I did not travel the mountain and the land on Point B and go back to Point A, I stopped at Point B so isn't my distance placement just 120m?

No, I didn't land on the other side. I started from Point A and climbed up the mountain and landed on Point B which is the point where I came down, and I stopped on Point B. And Point A to Point B distance is 120m.

If I am starting from Point A to travel on a mountain to Point B which is when I land down from the mountain, and I stopped there. I didn't go back to the mountain. The whole distance that I covered from walking to the mountain and coming down was 120m.

So your displacement is always how far away you land from your starting point. So in that case, what would be the displacement question of that mountain question I asked?

So for displacement, unless the person changed direction or course during their jouney, it will be zero? What if it a straight line of 500m, you just have to run that distance so you can't go back to your starting point. What would be the displacement then? The same thing as distance?

Oh yeah because I have to cover my whole walking distance, not just the distance between my my house and my starting. So my displacement would be 100m west??

Oh ok, so if I run to my house which is for example 400 m from me, and then I go back left (west) 300m, my distance is 400m but my displacement is 100m??

And what exactly is displacement? Isn't it the distance between your starting point and your finishing point? For example, if I climbed over a mountain then just for example, my distance is 120m, but the distance from Point A (starting point) to Point B (finishing point) is 20m so my...

Btw, what is velocity? I mean, I know what it is but I want to know it in very simple terms.

Yeah, thanks a lot. I really do wanna Physics for my HSC year, I thought of doing another subject as a back up for Year 12 if I don't wanna do Physics for my HSC year, but that subject which is CAFS I hate and regret choosing so much.

Are you in year 12? How do you find the subject? Lots of strategic thinking?

I'm fairly good at maths so as long as I can remember the formulas and know how to apply them, I should be fairly alright with the math problems. The reason I chose Physics is because I feel like I can understand it more than Chemistry or Biology which are so boring for me.
