Science Syllabus Physics Chemistry Biology Work and Energy Atom and Molecules Plant Tissue We are going to learn in just 10 Minutes Physics Work and its Unit. Energy and its Unit. Types of Energy Work and its Unit. What is Work? Work done in moving a body is equal to the product of force exerted on the body and the distance moved by the body in the direction of force. Force × Displacement = Work Example, thought that you push an object the object will move in straight line with only 1 speed, we will say that there is a work done. (socho tumne 1 car ko dhakka diya, vo car bilkul seedhe direction me move kari vo bhi 1 speed se...) "Force aur displacement ka direction same hona chahiye tab work kaha jaeyga!" What is Unit of Work? W = F × D Unit: Force = Newton ...
