Are you a Class X student of ICSE Board and preparing for your Board Exams than this is the right place for you to check your performance level. It will help you to give an idea about the question that comes in the Board Exam specially on the topic “WORK”. Work is a physical quantity. A force is doing work when it applied on a body so that their exist some displacement in the direction of the force applied. Through this you are able to check your command over the topic. As a Graduate I am setting this Physics ICSE Sample Papers for Class 10 on WORK for your help out in this regard. Some help has been taken from previous year Board sample papers and referred textbooks. So lets have a look on the type of questions asked in the exam specially on the topic WORK as per the latest pattern of ICSE Board.
