Detailed explanation-1: -Initial Velocity is the velocity at time interval t = 0 and it is represented by u.
Detailed explanation-2: -Formulas for Initial Velocity Thus velocity at which motion start is the initial velocity. Obviously, this velocity at time interval t = 0. It is represented by letter u.
Detailed explanation-3: -They are known as SUVAT equations because they contain the following variables: s-distance, u-initial velocity, v-velocity at time t, a-acceleration and t-time.
Detailed explanation-4: -the initial velocity of a body is u. It is under uniform acceleration. Its velocity v at any time given by a-(a)v=u+at2. (b)v=u+1/2at2(
Detailed explanation-5: -The same symbols are used for speed and velocity. When an object is changing speed/velocity, u is often used for the initial speed/velocity, with v being used for the final speed/velocity. The symbol c is usually reserved for the speed of light.
