v = dx/dt (the derivative of 'x' with respect to 't') where 'x' is the displacement of the object
in a given direction, and 't' is time.
There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.
The formula for velocity is (v = d/t) or (velocity = distance/time).
Velocity is distance / time
velocity = frequency / wavelength, I believe.
Final velocity v = u + at
v(t) = dsdt This should be the formula for instantaneous velocity.

There are, of course, several formulae that involve acceleration. The basic definition of acceleration is: acceleration = delta velocity / delta time, that is, to get average acceleration, divide the difference of velocity by the time that passed. The same formula also gives you the instant acceleration, if the acceleration is constant. If you want to get instantaneous acceleration, and the acceleration changes, then you need calculus: acceleration = dv / dt (that is, take the derivative of the velocity).
The formula for velocity is (v = d/t) or (velocity = distance/time).
Velocity is distance / time
velocity is distance/time
Final velocity = (Initial velocity) + (time)(acceleration)
Velocity=displacement(distance)/time.
Velocity (speed) = distance/time
velocity = frequency / wavelength, I believe.
Deceleration is the rate of decrease of velocity with respect to time. It is the negative of acceleration. The formula for deceleration is the same as that of acceleration, only that the acceleration is represented as negative. The formula is: - (deceleration) = (final velocity) - (initial velocity) time Therefore, (deceleration) = (initial velocity) - (final velocity) time
velocity is a vector quantity. Its magnitude is given by (velocity)= (distance)/(time)
