ইংরেজ বিজ্ঞানী স্যার আইজ্যাক নিউটন তার গতির তিনটি সূত্র দিয়ে মেকানিক্সের ভিত্তি স্থাপন করেছিলেন, যা বল, বস্তু এবং গতির মধ্যে সম্পর্ক বর্ণনা করে। গতিকে অনুবাদে আলাদা করা যেতে পারে, যেখানে একটি দেহ স্থান পরিবর্তন না করে অবস্থান পরিবর্তন করে, এবং ঘূর্ণন, যেখানে একটি দেহ তার গড় অবস্থান পরিবর্তন না করেই মহাকাশে স্থির একটি অক্ষের চারপাশে ঘোরে। কিছু চলমান শরীর বিশুদ্ধভাবে অনুবাদ করছে, অন্যরা বিশুদ্ধভাবে ঘোরানো, এবং অনেকে উভয়ই করছে।

The English scientist Sir Issac Newton established the foundation of mechanics with his three laws of motion, which describe the relation between forces, objects, and motion. Motion can be separated into translation, where a body changes position without changing its orientation in space, and rotation, where a body spins about an axis fixed in space, without changing its average position. Some moving bodies are purely translating, others are purely rotating, and many are doing both.

These are the current scores badges for this post were claimed with.

For example, if a badge has a score of 50, then you can claim it for yourself if your recording receives 51 points or more.

أسس العالم الإنجليزي السير إسحاق نيوتن أساس الميكانيكا بقوانينه الثلاثة للحركة ، والتي تصف العلاقة بين القوى والأشياء والحركة. يمكن فصل الحركة إلى ترجمة ، حيث يغير الجسم موضعه دون تغيير اتجاهه في الفضاء ، والدوران ، حيث يدور الجسم حول محور ثابت في الفضاء ، دون تغيير متوسط موضعه. بعض الأجسام المتحركة تترجم بحتة ، والبعض الآخر يدور فقط ، والعديد منهم يفعل كلا الأمرين.

Die Engelse wetenskaplike Sir Issac Newton het die grondslag van meganika gevestig met sy drie bewegingswette, wat die verband tussen kragte, voorwerpe en beweging beskryf. Beweging kan geskei word in translasie, waar 'n liggaam van posisie verander sonder om sy oriëntasie in die ruimte te verander, en rotasie, waar 'n liggaam om 'n as vas in die ruimte draai, sonder om sy gemiddelde posisie te verander. Sommige bewegende liggame is suiwer vertaal, ander is suiwer roterend, en baie doen albei.

Các loại nhiên liệu thương mại chính được sử dụng trên toàn thế giới ngày nay là khí đốt tự nhiên, xăng, nhiên liệu hàng không, dầu diesel, dầu nhiên liệu và nhiên liệu rắn như than đá. Các nhiên liệu hóa thạch thương mại này có thể được thay thế bằng nhiên liệu sinh học và nhiên liệu rắn có nguồn gốc từ sinh khối bằng cách sử dụng các công nghệ chuyển đổi. Có các nguồn sinh khối cụ thể phù hợp với từng công nghệ chuyển đổi. Ví dụ, cây đường là nguyên liệu tốt để chuyển hóa cồn sinh học, và dầu đậu nành là nguyên liệu lý tưởng để sản xuất dầu diesel sinh học.

The major commercial fuels used worldwide today are natural gas, gasoline, aviation fuel, diesel, fuel oils, and solid fuels such as coal. These commercial fossil fuels could be replaced with biofuels and solid fuels derived from biomass by using conversion technologies. There are specific biomass resources that are well-suited to each conversion technology. For example, sugar crops are good feedstock materials for bioethanol conversion, and soybean oil is ideal for biodiesel production.
