Scalars and vectors
Form 3: Scalars and Vectors Hello, students! Today, we're going to explore an essential concept in physics— Scalars and Vectors . These are fundamental in describing quantities and understanding motion. Let's start with the basics. 1. Definitions and Examples: Scalars: These are quantities that have only magnitude (size) and no direction. Examples include mass, temperature, and speed. Example: If you tell someone your weight is 70 kilograms, you've provided a scalar quantity. Vectors: These are quantities that have both magnitude and direction. Force, velocity, and displacement are examples of vectors. Example: If you say you are walking with a speed of 5 meters per second eastward, you've given a vector quantity. 2. Resultant of Coplanar Vectors using Graphical Method: When dealing with coplanar vectors (vectors lying in the same plane), the graphical method helps us find the resultant. This involves placing vectors head to tail and connecting the initial point o...
