How To Calculate Initial Velocity

Initial velocity is a crucial concept in physics, essential for understanding motion and calculating displacement. This calculator helps you determine initial velocity with ease.

1. Enter the initial position, final position, and time in the respective fields.
2. Click ‘Calculate’.
3. View the result and chart below.

The formula for initial velocity (u) is:

u = (x_f – x_i) / t

where x_f is the final position, x_i is the initial position, and t is the time.

Comparison of Velocities

Scenario	Initial Velocity (m/s)
Case 1	5.2
Case 2	3.7
Case 3	7.1

• Always use consistent units for accurate results.
• Consider the direction of motion when calculating velocity.

What if the final position is the same as the initial position?

The initial velocity is 0 m/s.

Can I calculate initial velocity with negative values?

Yes, negative values indicate motion in the opposite direction.
