If s is the displacement vector of an object at time t, then
velocity = ds/dt, the derivative of s with respect to t
and speed = |ds/dt|, the absolute value of the velocity.

Since speed or velocity = distance/time ,its dimensional formula =L/T = [MoLT-1]
The physics formula for speed is s = d x t whered is the distance traveled in a period of timet is the amount of time it took to travel the distances is the speed traveled
velocity= distance/time=d/t accelaration= dv/dt
S is usually used for position and v for velocity or speed.
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
