Physics Spmnetic!™ 🔭

Tips Fizik Cara nak tau berkadar langsung / sonsang berdasar rumus How to determine it is directly proportional / inversely proportional Contoh : ⬆️ y = XD ⬆️ d ⬇️ y = XD         d⬇️ Tips : 1) effect di y , di belakang yang akan menentukan sama ada y tu ⬆️ or ⬇️ 2) salah 1 constant/Pemboleh ubah je boleh beri kesan... 3) ⬆️ meningkat / increases ⬇️ menurun / decreases 4) 🗂 kalau bermanfaat, boleh tulis dalam nota ok 🔖 Tips by @spm2033 #tipsspmhere

Good luck kepada sesiapa yg exam esok! Do your best!!

WHY DON'T WE FEEL THE EARTH MOVE? Every day we stand, sit, sleep on the earth without feeling anything strange. whereas the earth is moving insanely fast — spinning on its axis at about 1,670 km per hour and orbiting the sun at a speed of 107,000 km per hour. Dear sirs and madams, why don't we feel all that? the answer: because everything happens regularly and consistently, like we are in a smooth moving train — as long as we don't brake, turn or crash, we won't even notice that the train is moving. Not only that, we, the atmosphere and all things on earth actually move at the same speed. That's why when we jump, we don't 'fall behind'. This is called the principle of inertia — an object in motion will continue to move unless there is an external force, so all the movements of the earth happen in harmony, until our brain considers it 'normal'. But if the earth suddenly stops suddenly — even for a moment — the impact is like everything flying out. Fortunately, physics with the permission of God Almighty does not allow such things to happen without a big reason So, continue living as usual... even though we are actually 'gliding' in space in the most elegant style.

KENAPA KITA TAK RASA BUMI BERGERAK? Setiap hari kita berdiri, duduk, tidur atas bumi tanpa rasa apa-apa pelik. padahal bumi tengah bergerak gila laju — berpusing pada paksinya sekitar 1,670 km sejam dan mengorbit matahari pada kelajuan 107,000 km sejam. Taaaaaapiiii tuan tuan dan puan puan yang dihormati sekalian, kenapa kita tak rasa pun semua tu? jawapannya: kerana semuanya berlaku secara tetap dan konsisten, macam kita dalam kereta api yang gerak lancar — selagi tak brek, belok atau langgar, kita takkan perasan pun kereta tu tengah meluncur. Bukan tu je, kita, atmosfera dan semua benda di atas bumi sebenarnya bergerak sama laju. Sebab tu bila kita lompat, kita tak 'tertinggal' ke belakang. Ini dipanggil prinsip inersia — benda yang tengah bergerak akan terus bergerak melainkan ada daya luar, jadi semua pergerakan bumi berlaku secara harmoni, sampai otak kita anggap itu 'normal'. Tapi kalau bumi tiba-tiba berhenti secara mengejut — walau sesaat — impaknya macam semua benda terbang keluar. Nasib baik fizik dengan izin Allah Taala tak benarkan benda macam tu berlaku tanpa sebab besar So, teruskan hidup macam biasa... walaupun sebenarnya kita tengah ‘meluncur’ dalam angkasa lepas dengan gaya paling elegan.

Please forgive me if there are any wrong or weird physics term. I only use Google translate to translate it from malay to English 😭

Why was Bernoulli wrong? Submarines don't use Bernoulli's principle because that principle deals with fluid flow and pressure — typically used in airplanes, wings, and water pipes, not things that sink or float in fluids. So, submarines float and sink due to changes in buoyancy (Archimedes), not flow pressure (Bernoulli).

Kenapa Bernoulli salah? Kapal selam tak guna prinsip Bernoulli sebab prinsip tu berkaitan dengan aliran bendalir dan tekanan — biasanya digunakan dalam kapal terbang, sayap, dan paip air, bukan benda yang tenggelam atau terapung dalam bendalir. Jadi, kapal selam terapung dan tenggelam sebab perubahan daya apungan (Archimedes), bukan tekanan aliran (Bernoulli).
