LIMITATIONS OF DIMENSIONAL ANALYSIS? |
(i) The method does not provide any information about the magnitude of dimensionless variables and dimensionless constants. (ii) The method cannot be used if the quantities depend upon more than three-dimensional quantities: M,L and T. (iii) The method is not applicable if the relationship involves trigonometric, exponential and logarithmic functions. |

unit vector? |
A unit vector is a vector that has a magnitude of exactly 1 and specify a particular direction. |
|
|
scalar product of two vectors |
The scalar product of two vectors is defined as the product of the magnitude of two vectors and the cosine of the smaller angle between them. |
|
|
vector product |
The vector product of two vectors is defined as a vector having a magnitude equal to the product of the magnitudes of the two vectors and the sine of the angle between them. |
|
|
average velocity |
The average velocity is the ratio of the change in displacement that occurs during a particular time change interval. It is a vector quantity. |
|
|
average speed |
The average speed is the ratio of the total distance covered by a particle to the change in time. |
|
|
position vector |
The position vector ⃗ is used to specify the position of a particle in space. |
