### What is the formula for the final velocity?

There are a number of different formulas for final velocity.
Each one describes the
relationship between final velocity and other kinematic
quantities, such as initial
velocity, initial and final position, acceleration, and time.
Depending on what
information you have, you would select the most appropriate and
useful formula.

### What is the meaning and formula for deceleration?

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

### What is the formula for calculating final velocity when you know the initial speed and the acceleration?

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.

### Velocity formula?

Velocity: The changes happen in position is called
velocity. Velocity is considered as the physical quantity. The
magnitude and direction are necessary for this velocity.
Velocity Formula
:
Unit: metre/second
The formula for velocity is,
`v=d/t`
Here, the displacement is denoted as d and the time of the
displacement is denoted as t.
Velocity = change in position over a specific time interval
v= (xf - xo)/(tf - to)
where xf is the final position and xo is the initial
position.
where tf is the final time and to is the initial time.

### What is the formula for deceleration?

The first answer is backward. Acceleration = (final velocity -
initial velocity)/total time. For deceleration the formula is the
same, the answer will just be negative.
Agreed. In physics, there is no "deceleration", only negative
acceleration.
a = Δv / Δt
There is no equation for "deceleration" as suggested below.
Deceleration=(original velocity-final velocity)/Time
Deceleration In Motion
Deceleration = inital speed - final speed / total time
