Roller Blade

Satu hari tu saya ada ternampak satu kasut roda. Yang saya tahu saya kasut roller blade ni lebih kurang macam ice skating. Jadi saya nak try pakai roller blade tu and then cuba main. Lepas saya pakai, saya cubalah bangun. Alhamdulillah saya tak jatuh. And then saya try jalan. Masa tengah jalan tu saya cuba imbangkan badan supaya tak jatuh and then saya rendahkan sedikit lutut saya supaya saya dapat area yang lebih besar. So, daripada apa yang saya ceritakan ini, saya dapat tahu bahawa hukum fizik yang saya gunakan adalah conservation of momentum. Sekian.

Physics concept that wow me the most :)

For me, I don't have any interesting things related to physics to tell or should I say I do not know whether the things I experienced was actually related to physics. I simply learned them for now and I'm hoping I will discover amazing things from now on.

Did you guys know that the Aurora Borealis which is one of our most beautiful phenomena in the world is related to physics? If you guys don't have any idea for what I'm talking about, I'm going to provide a picture. It is also known as the Northern Lights. It has always amazed people since it was first discovered as it was so unique.

This phenomenon occurred when the sun gives off high energy charged particles called ions that travel into space at the speed of 300 to 1200 kilometres per second which is really fast. A cloud of the charged particles is called plasma. The stream of plasma that came from the sun is called the solar wind. As the solar wind interacts with the edge of the earth's magnetic field, some of the particles are trapped thus following the lines of the magnetic force down into the ionosphere. The ionosphere is the section of earth's atmosphere that extends from about 60 to 600 kilometres above the earth's surface. When the particles collide with the gases in the ionosphere, they started to glow producing the auroras light that we know as Aurora Borealis.


                 
                                       

Assalamualaikum and hi guys

Sorry for lambat post so sorry

Ok natural phenomena

🤔🤔🤔🤔🤔🤔

My brothers and I go for a breakfast. 

We ordered cold Milo and hot tea. 

When I took ice from the Milo and take it 

into the tea the ice gone in a few seconds. 

So, I asked my little brother why. 

He said that he doesn't know and 

I say it just want to stable their temperature 

and my brother was like wowwww. 

Correct me if im wrong. 

mirage :)

I love to follow my mom to her working sites. mostly at the noon. As I looked around, the road, vehicles and paddy field, suddenly I looked at something. It caught my eyes. I saw like a line of water on the road from afar and when we drove closed to it, it disappeared! How cool is that! Then I knew from what I have learnt at school, it was a mirage. 

" Mirages happen when the ground is very hot and the air is cool. The hot ground warms a layer of air just above the ground. When the light moves through the cold air and into the layer of hot air it is refracted (bent). A layer of very warm air near the ground refracts the light from the sky nearly into a U-shaped bend." - source from internet.

                            - source from internet.

So, since then I will look up for the mirage whenever I'm in a car during sunny afternoon. It attracts me more and more about physics.

Road To Be A Physicist

Assalammualaikum dan salam muafakat Johor,

Cerita saya mungkin jauh berbeza daripada rakan-rakan sekelas yang lain kerana sejujurnya saya tidak mempunyai sejarah atau pengalaman yang membuatkan saya tertanya-tanya tentang fizik.

Ketika berada di tingkatan 4 dan 5, fizik merupakan antara subjek yang mudah untuk diskor berbanding subjek kimia dan biologi. Saya mula meminati fizik apabila meyedari terlalu banyak fenomena alam dan aktiviti harian kita yang berkaitan dengan fizik. Contohnya, tekanan. Tekanan (simbol: P) ialah sukatan daya yang bertindak ke atas luas permukaan sentuh, atau daya per unit luas dalam arah yang berserenjang dengan permukaan berkenaan. Semakin kuat daya yang bertindak ke atas permukaan yang diberikan, semakin tinggi tekanan. Begitu juga semakin kecil luas permukaan yang disentuh oleh daya berkenaan, maka lebin tinggi tekanan. Sejak mempelajari tekanan, barulah saya faham mengapa ketika menyiram pokok atau membasuh lantai, air akan menjadi deras atau laju jika kita mengecilkan luas permukaan muncung hos air. Selain itu, apabila hujan dan angin kuat, kemungkinan payung yang kita pakai akan menjadi terbalik. Hal ini kerana tekanan dibawah payung yang lebih tinggi menolak payung keatas. Konsep fizik yang menarik ini menimbulkan minat saya untuk mempelajari fizik dengan lebih lagi.

Subjek 'Introduction To Physics' ini menjadikan saya lebih suka berfikir dan memerhati alam sekeliling dan magaitkannya dengan konsep fizik. Sebagai contoh, ketika saya baring di atas katil, saya terfikir mengenai graviti dan luas permukaan kaki katil yang stabil menyebabkan saya tidak jatuh ke bawah atau terapung. Perkara ini pernah diterangkan oleh rakan saya Aqilah dan Mar didalam kelas. Saya begitu teruja apabila dapat mengaitkan apa yang dibelajar didalam kelas dengan kehidupan seharian.

Saya berharap saya dapat mempelajari fizik dengan lebih lanjut supaya saya dapat mengaplikasikannya dalam aktiviti harian.

Maizatul Aqmarisha :)

BASKETBALL & PHYSICS 🏀

Basketball had taught me a lot about physics actually. Im started to play basketball since form 1 (obviously because im a little bit taller). My previous coach was an english teacher but she was the one who convince me about how physics related to these game. 

SHOOTING
Projectile Motion: The trajectory path when shooting a basketball is very significant. There is a horizontal axis to show projectile motion, also known as the x-axis. This axis represents the distance the basketball travels, which increases over time. There is a second axis that is vertical, which is the y-axis. The y-axis commonly represents the height that the player is, along with the height of the ball. As you're shooting a basketball, our brains calculate these things, which helps us score! 

SHOES
The shoes you wear when playing basketball do matter.(compared to any sport shoes) This is due to the friction on the ground. Basketball shoes must have good traction to avoid slipping. 

WOW WHAT?

Hey guys,

They said we heard all those mystic sounds because of physic. Creepy isn't it? the question is why we always heard all those laughing sounds, kids crying, dogs barking and many more only at night. When I was in foundation program, my physic lecturer, Madam Asyikin told us you heard them because of physic, he said “ if you want to be a ghost buster, you must learn physic” and we burst to laugh. How funny it is. hahahahaha.

                Guess what, its true because of the refraction of sound wave.  Sound wave will reflect faster on hot air compare to cold air. At night the temperature of air at the Earth’s surface is much hotter compare to the atmosphere. This cause sound wave that travel that travel to the Earth’s surface reflect downward. So, we can hear clearly at night even though the sounds is far away from us.  

                That’s all from me :)

p/s : correct me if I’m wrong
