one dimensional vectors

. In addition to this, the direction of the position vector gives the direction q in which P lies, as observed from 0. It is important to note that position vectors are different for different positions of the particle. The above explanation can be extended to a three dimen..

Which solid can be represented as a three dimensional picture using the figure and vector? => pyramid or sphere or cylinder or circle..

It is the term which tells about the power with which a fundamental quantity is contained in a physical quantity. E.g., Dimensional formula of velocity is [LT - 1 ], that of density is [ML - ..

Which solid can be represented as a three dimensional figure using the given figure and vector? => cuboid or trapezoid or cone or rectangle..

. The displacement vector is independent of the choice of the origin. We have, Thus, displacement vector is the difference between two position vectors. If (x 1 , y 1 ) (x 2 , y 2 ) are the coordinates of P and Q respectively, the..

Head-on Elastic Collision [One Dimensional Elastic Collision] - It is that elastic collision in which the colliding bodies move along the same straight line before and after the collision. Consider two bodies A and B of masses m 1 and m 2 respectively, moving along the..

= c = ab sin f ...... (i) Where, f is the angle between a and b, the direction of , the vector product ..

Dimensional equations are used to validate the correctness of a physical equation. Dimensional equations are used to derive correct relationship between different physical quantities. Dimensional equations are used to convert one system of units to an..

Dimensional analysis has no information on dimensionless constants. If a quantity is dependent on trigonometric or exponential functions, this method cannot be used. In some cases, it is difficult to guess the factors while deriving the relation connecting two or more physical qua..
