WebAns: Work is said to be done when a force acts on a body and moves it in the direction of the force. Greater is the force acting on a body and longer is the distance moved by it, larger would be the work done. Mathematically, Work is a product of force F and displacement S in the direction of the force. Thus. Work done = Force x displacement. #include iomanip setwWebChapter 11 class 9th science Work and energy कक्षा 9 विज्ञान अध्याय 11 प्रश्न उत्तर तथा नोट्स #work #energy #numerical. #include bits dc++.hWebDocument Description: Work and Energy - PowerPoint Presentation, Science, Class 9 for Class 9 2024 is part of Class 9 preparation.
