Science: Throwing a ball, lifting a heavy object or stopping a moving thing, all of these activities require an application of force. And what do we mean by force? Force can be defined as actions that we perform on various objects in order to move them. Force is associated with the concept of pressure. How are these concepts connected with one another? Let's explore! Math: What do we get when we multiply 2 with 2? The answer is 4. What do we get if we multiply 7 with 7? The answer is 49. We multiplied the same number twice to get an answer. The answer that we get by multiplying the number twice is called 'Square' of a number. But what if we multiply the same negative numbers with each other? Do we get a negative square? Let's explore.
