Kinematics Explained
- v = d / t
- a = (v - u)/t (u: initial velocity)
- d = ut + (1/2)at²
- v² = u² + 2ad
- Vector magnitude: |v| = √(vx² + vy²)
Velocity Calculator – Instantly Calculate Speed, Time & Distance
Whether you’re solving physics homework or tracking the motion of a moving object, knowing velocity is key. With our Velocity Calculator, you can quickly determine how fast something is moving using distance and time—or even calculate time and distance if you already know the velocity. It’s accurate, fast, and ideal for both science and everyday use.
🔍 What Is Velocity?
Velocity refers to the rate of change of position over time—with direction included. It’s more than just speed; it tells us how fast and in what direction an object is moving.
For example:
- Speed: 60 km/h
- Velocity: 60 km/h to the north
This difference matters in physics, engineering, and even driving.
📐 Velocity Formula
The most common velocity formula is:
Velocity (v) = Distance (d) ÷ Time (t)
You can rearrange it to find:
- Distance: d = v × t
- Time: t = d ÷ v
These formulas help you solve for any one of the three variables when the other two are known.
⚙️ How to Use the Velocity Calculator
The calculator is very simple:
- Choose which variable to solve for: velocity, time, or distance
- Enter the known values (for example, time and distance)
- Click Calculate
- Get your result in meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph)
It’s that easy!
📊 Example Calculation
Scenario: A car travels 120 kilometers in 2 hours. What is its velocity?
- Distance = 120 km
- Time = 2 hours
- Velocity = 120 ÷ 2 = 60 km/h
So, the car was moving at a velocity of 60 km/h.
