The quantities which have both magnitude and direction are called vectors. Examples are velocity, force, displacement, weight, acceleration, etc. The quantities which have only magnitude and no direction are called scalar quantities. Examples are mass, volume, speed, time, frequency, etc.
Jan 13, 2021 · A physical quantity which has both magnitude and direction and obeys the rules of vector algebra is known as vector or vector quantity. It is denoted by alphabetical letter (s) with an arrow- head over it. Electric current and pressure have both magnitude and direction but they do not obey the rules of vector algebra.
In Maths, Vectors are objects that have both magnitudes as well as directions. Learn the definition, notation. Addition, subtraction of vectors, unit vectors, scalar and dot product, components of vectors, applications and solved problems at BYJU’S.
Vectors Questions with Solutions. Magnitude of Vectors. To find the magnitude of a vector, first find the sum of the squares of the vector components and finally take the square root to the obtained value. If A is the vector with the components (x, y, z), then the magnitude of vector A is found using the formula,
Jul 14, 2021 · This post covers Vectors class 11 Physics revision notes – chapter 4 with concepts, formulas, applications, numerical, and Questions. These revision notes are good for CBSE, ISC, UPSC, and other exams.
Vector of Class 11. Definition: The physical quantities specified completely by their magnitude as well as direction are called vector quantities. The magnitude and direction alone cannot decide whether a physical quantity is a vector.
Definition 1 A quantity that has magnitude as well as direction is called a vector. Notice that a directed line segment is a vector (Fig 10.1(iii)), denoted as uuu AB r or simply as a r , and read as ‘vector AB uuu r ’ or ‘vector a r ’.
Learn what vectors are and how they can be used to model real-world situations. Perform various operations with vectors like adding, subtracting, scaling, conversion between rectangular to polar coordinates, etc.
