>Similarly, by referring to the figure belo..Equality of Vectors
> If the scales selected for the representation of three vectors are the same, then, three equal vectors are represented by three arrows of equal lengths, pointing in the same direction. If, however, the scales chosen are different, then, it is possible to represent equal v..
Expression for Velocity Vector
Expression for Velocity Vector - The curved line in the figure represents the trajectory of a particle. Let the particle be at P at time t. The position of p with reference to origin O is given by . Let the particle be at Q at time (t + D t). The position of Q with reference to ..

Free vector
Free vector is that vector whose initial point or tail is not fixed. It is also known as a non-localised vector. For example, velocity vector of particle moving along a straight line is a free vector..
Dot Product of Vectors and the Resolution of a Vector
It was mentioned earlier that, displacement vectors are added to displacement vectors, or velocity vectors are added to velocity vectors. Just as it is meaningless to add scalar quantities of different kinds, such as mass and temperature,..
The Zero Vector and its Properties
>The velocity vector of a stationary body is a zero vector. The acceleration vector of a body in uniform motion is a zero vecto..
Scalar Multiple of a Vector
Multiplication of Vectors by Real Numbers, i.e., Scalar Multiple of a Vector - The multiplication of a vector by a real number assumes a lot of significance in such statements as - velocity of car B is double the velocity of car A l . When a ve..
