Question

What is u in Physics?

Answer 1

u in Physics:

1. The letter u is used in physics to denote the sign of potential energy, as well as the initial velocity and the object distance in ray optics.

In the equation $v=u+at,$

1. The initial velocity is $u$.
2. The final velocity is denoted by $v$.
3. $a$ stands for acceleration.
4. The time period is denoted by the letter $t$.

From the standpoint of acceleration, the above equation is derived. (It can also be deduced from a graph of velocity and time.)
