Detailed Solution
Download Solution PDFধারণা:
- গতিশক্তি: m ভরের শরীরকে একটি বিন্দু থেকে অন্য বিন্দুতে উল্লিখিত বেগ দিয়ে সরানোর জন্য যে শক্তির প্রয়োজন হয় তাকে গতিশক্তি বলে।
গতিশক্তি এইরূপেও প্রদত্ত হতে পারে:
K.E = ½ × m V2
যেখানে K.E = গতিশক্তি
m = বস্তুর ভর
V = একটি বস্তুর বেগ
গণনা:
প্রদত্ত যে, m = 22 কেজি, v = 5 মিটার/সেকেন্ড
∴ K.E = ½ × 22 × 52
K.E = 275 J
অতএব, বস্তুর গতিশক্তি হল 275 J
