Question

What are the two components of velocity?

Answer 1

Velocity is a vector quantity which is equal to the rate of displacement with respect to the time and it acts in a particular direction. If velocity applies in a diagonal direction, then we need to resolve it into horizontal and vertical direction to solve complicated problems.

Complete answer:
Velocity defines the speed with which an object moves and having a particular direction. Velocity is a vector quantity. One-dimensional motion is simplistic, but the two-dimensional motion is complicated since the velocities can lead diagonally with velocity v.
For example, a ball could be moving horizontally and vertically simultaneously with a diagonal velocity. We split up the velocity vector, v, of the ball into two separate horizontal, ​$v_{x}$, and vertical directions $v_{y}$ to simplify our calculations.

Splitting up the diagonal velocity v into horizontal,$v_{x}$ and vertical $v_{y}$, elements enable us to deal with each direction separately. Naturally, we will be able to turn one complicated two-dimensional dilemma into two lightly one-dimensional problems.

Additional Information:
Initial velocity represents how fast an object moves when gravity first implements force on the object. On another hand, the final velocity is a vector term that measures the distance rate concerning the time and direction of a traveling body after it has attained its highest acceleration.

Note:
The velocity gives us a concept of how speedy or delayed an object is moving. We come across conditions where we need to know which of the two or more objects is traveling faster. One can quickly tell the faster of the two if they move in the same direction on the identical road. However, if their direction of movement is in the reverse direction, it is not easy to define the fastest.
