VECTOR TUTORIAL What is a vector? For introductory physics, a vector is an entity having the characteristics of magnitude and direction. Since vectors are used throughout physics and engineering, we must learn how to add, subtract, multiply, and divide vectors. If we take a vector v and multiply it by the scalar 3, we get another vector whose magnitude has increased by a factor of 3. The vector’s direction does not change. For example, r = v t. The position vector, r , is in the same direction as the velocity vector, v . The scalar t does not affect the direction of the vector. A vector times a scalar always yields a vector in the same direction as the original vector. Its magnitude will change if the scalar does not have a magnitude of one. A vector divided by a scalar also produces a vector in the same direction as the original. How do we add/ subtract two or more vectors that point in different directions? How do we multiply or divide vectors that point in different directions? We need to find the parts
