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..
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..

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,..
Resultant velocity of oblique projectile
We have, Applying the law of parallelogram of vectors, Since, This equation gives the magnitude of the resultant velocity of the projectile at any time. The direction of the projectile is given by the angle equation, which the resultant velocity v makes with the horizo..

Explained everything so well and did everything quickly.Amazing tutoring. My most favourite. Helped me a lot! :D
Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
It was extremely helpful and was able to organize the information in easy to understand ways - Faith
Very informational yet simple and easy to comprehend. Tutor Vista is helping me a lot.
