Rules of Geometrical Addition of Vectors Geometrical Method: Two similar vectors can be added or subtracted. For example, displacement can be added only with displacement.…

Displacement Vector: Distance traveled by a point along a linear or straight path is called the displacement vector. It is a vector which gives the…

Radius Vector: The distance of a point from the origin is called Radius Vector. It is denoted by, ř. Explanation: Here, the distance of the…

Suppose, two persons at the ends of a rope are pulling with the same force. Then the resultant of that tension will be a null…

A vector is needed in order to know the position of a point in the reference frame. The position of the body can be determined…

The direction represented by the normal drawn on a plane or surface is the vector of that surface. In this case the plane is the…

Unit Vector: A vector whose magnitude is unity is called a unit vector. When a vector of non-zero magnitude is divided by its magnitude it…

Angular velocity If the time interval approaches zero, the rate of change of angular displacement with time is called instantaneous angular velocity or angular velocity…

Angular momentum The vector product of the radius vector and the linear momentum of a revolving particle is called angular momentum. Explanation: Suppose ř =…

A vector quantity is expressed in two ways by sign; e.g. by letter or by straight line. By letter a vector quantity can be divided…
