About Velocity Calculator

The Velocity Calculator is a comprehensive physics tool that calculates velocity (speed) from distance and time, with support for multiple calculation modes and instant unit conversions. Whether you need average velocity, relative velocity between two objects, or angular-to-linear velocity conversion, this calculator provides step-by-step solutions with visual feedback.

Velocity Formulas

Velocity describes how fast an object changes its position. The core formulas used by this calculator are:

AVERAGE VELOCITY

$$v = \frac{d}{t}$$

ANGULAR → LINEAR

$$v = \omega \times r$$

How to Use This Calculator

  1. Choose a calculation mode: Select from five modes — Average Velocity (v = d/t), Find Distance (d = v×t), Find Time (t = d/v), Relative Velocity, or Angular to Linear conversion.
  2. Enter your known values: Input the measurements with their appropriate units. Use the dropdown selectors to pick the right unit for each value.
  3. Click Calculate: The calculator solves for the unknown and shows step-by-step work with MathJax-rendered formulas.
  4. Review conversions: Results are automatically displayed in m/s, km/h, mph, ft/s, and knots, so you can quickly compare across unit systems.

Understanding Velocity vs. Speed

Speed is a scalar — it only tells you how fast something moves. Velocity is a vector — it includes both magnitude and direction. In everyday language they are often used interchangeably, but in physics the distinction matters. This calculator computes the magnitude of velocity (equivalent to speed for straight-line motion).

Frequently Asked Questions

What is the formula for velocity?

The basic formula for average velocity is v = d / t, where v is velocity, d is displacement (distance), and t is time. This gives the rate of change of position over a period of time. For instantaneous velocity, calculus is used: v = dx/dt.

What is the difference between speed and velocity?

Speed is a scalar quantity that measures how fast an object moves (always positive), while velocity is a vector quantity that includes both magnitude and direction. Speed is the magnitude of velocity. For example, 60 km/h is a speed, but 60 km/h north is a velocity.

How do you convert between velocity units?

Common conversions: multiply m/s by 3.6 to get km/h, multiply m/s by 2.237 to get mph, multiply km/h by 0.6214 to get mph. For example, 10 m/s = 36 km/h = 22.37 mph.

What is relative velocity?

Relative velocity is the velocity of one object as observed from another moving object. When two objects move in the same direction, relative velocity equals the difference of their speeds. When they move in opposite directions, relative velocity equals the sum of their speeds.

How do you convert angular velocity to linear velocity?

Linear velocity equals angular velocity multiplied by the radius: v = ω × r. Angular velocity must be in radians per second. To convert RPM to rad/s, multiply by 2π/60.
