Basic Concept of Scalars and Vectors
Scalars and vectors are basic concepts in physics. Many problems in physics require to distinguish between scalar and vector quantities to apply the correct mathematical and conceptual approaches. Understanding scalars and vectors help us to grasp how Physics applies to real-world situations, such as calculating the total distance travelled (scalar) or determining the magnitude and direction of force (vector). Learning these concepts develops critical thinking and problem-solving skills. This chapter is primarily concerned with vector algebra and its application in uniform accelerated motion, in a straight line, motion of freely falling bodies in uniform gravitational field, projectile motion, and interaction between objects in one and two dimensions.
