Initial Velocity Calculator

Enter values in the given input box to calculate velocity using this initial velocity calculator.

Formula v0  = v - at

Is This Tool Helpful?



Equation for Velocity:
v = v0 + at

Initial Velocity formula:
v0 = v − at

a = v − v0/t

t = v − v0/a

v = Velocity,
v0 = Initial Velocity
a = Acceleration,
t = Time.

The velocity calculator is widely used in the field of physics. It has the utmost importance in the area of physics because students and scientists use this velocity finder on daily basis. The velocity vector calculator can calculate the:

  • Velocity
  • Initial velocity
  • Time, and
  • Acceleration

Keep on reading if you want to learn how to find velocity without using initial speed calculator, velocity definition, how to find initial velocity with acceleration and time, what is the formula for velocity and velocity equations.

What is velocity?

Velocity refers to the speed in a given direction. It is a vector measurement of the rate and direction of motion. The scalar absolute value (magnitude) of the velocity vector is the speed of the motion. Velocity is denoted by the symbol 'v'.

Velocity is a vector physical quantity; both magnitude and direction are required to define it. The advanced online Velocity Calculator is used to calculate the velocity when initial velocity, acceleration, and time are known.

How to calculate velocity?

Apart from calculating velocity using the magnitude of velocity calculator, we can manually calculate it using the velocity formulas in physics.

Let’s find the velocity with an example.

Calculate the velocity of an object having an initial velocity of 10 m/s, and gained the acceleration of 5 m/s2 in 15 seconds.


Step 1: Identify the given values.

v0 = 10 m/s

a = 5 m/s2

t = 15 sec

Step 2: Apply formula

v = v0 + at
v = 10 +5*15
v = 10+75
v = 85 m/s

Velocity (v) = 85 m/s

By using the same method and formula, you can calculate the initial velocity as well.
