Question
What is the abbreviation used for initial velocity and final velocity?
- U, V
- V, U
- u, v
- v, u
Hint:
Initial velocity=u and final velocity =v
The correct answer is: u, v
The abbreviations u and v are supposedly taken for initial and final velocity respectively to make it easier for numerical solving.
