فارسی: مثالي از انرژي مکانيکي:اگر دايره را با مدلسازي به ماهواره اي تشبيه کنيم داريم:"ماهواره در مدارهاي معين و تندي ثابت دور زمين ميچرخند,همانطور که ميدانيم نيروي خالصي(نيروي وزن) همواره بر ماهواره وارد ميشود اما چگونه امکان دارد با وارد شدن نيرو وزن به ماهواره,انرژي جنبشي و شتاب آن ثابت باقي بماند؟
پاسخ:"نيروي خالص وارد بر ماهواره عمود بر جهت جابه جايي است پس کار کل ماهواره صفر است,از طرفي با توجه به قضيه کار و انرژي تغييرات انرژي جنبشي نيز صفر است پس انرژي جنبشي و شتاب ثابت باقي ميماند." منبع GIF:ویکی پدیای انگلیسی |
