1. What is Velocity?

Definition: Velocity is a vector quantity that refers to the rate at which an object changes its position.

Key Aspects: It includes both speed and direction (making it different from speed which is scalar).

2. The Velocity Formula

The calculator uses the formula:

Where:

• \( v \) — Velocity (meters per second, m/s)
• \( \Delta x \) — Displacement (meters, m)
• \( \Delta t \) — Time interval (seconds, s)

Explanation: Velocity is calculated by dividing the change in position (displacement) by the change in time.

3. Importance of Velocity Calculation

Applications: Used in physics, engineering, sports science, transportation planning, and many other fields to analyze motion.

4. Using the Calculator

Tips: Enter the displacement in meters and time interval in seconds. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between velocity and speed?
A: Velocity includes direction (vector quantity) while speed is just how fast something is moving (scalar quantity).

Q2: What if I get negative velocity?
A: Negative velocity indicates motion in the opposite direction of your reference frame.

Q3: How is this different from average velocity?
A: This calculates instantaneous velocity if Δt is very small, or average velocity over the time interval.

Q4: What units should I use?
A: The calculator uses meters and seconds, but the formula works with any consistent units (km/h, miles/h, etc.).

Q5: Can velocity be zero while speed isn't?
A: No, zero velocity means zero speed. However, speed can be constant while velocity changes (if direction changes).
