1. What is Velocity?

Velocity is a vector quantity that refers to the rate at which an object changes its position. It includes both the speed of the object and the direction of its motion. The standard unit of velocity is meters per second (m/s).

2. How Does the Calculator Work?

The calculator uses the velocity equation:

Where:

• \( v \) — Velocity (m/s)
• \( s \) — Displacement (meters)
• \( t \) — Time (seconds)

Explanation: Velocity is calculated by dividing the displacement (change in position) by the time taken for that change to occur.

3. Importance of Velocity Calculation

Details: Calculating velocity is fundamental in physics and engineering for understanding motion, designing transportation systems, analyzing sports performance, and many other applications where motion is involved.

4. Using the Calculator

Tips: Enter displacement in meters and time in seconds. Both values must be positive numbers. The calculator will compute the velocity in meters per second (m/s).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between speed and velocity?
A: Speed is a scalar quantity (magnitude only) while velocity is a vector quantity (magnitude and direction).

Q2: Can velocity be negative?
A: Yes, negative velocity indicates motion in the opposite direction from the reference point.

Q3: What are typical velocity units?
A: Common units include m/s (SI), km/h, mph (miles per hour), and knots (nautical miles per hour).

Q4: How is instantaneous velocity different?
A: Instantaneous velocity is velocity at a specific instant, while average velocity is total displacement divided by total time.

Q5: What's the velocity of light?
A: The speed of light in a vacuum is approximately 299,792,458 m/s (often rounded to 3×10⁸ m/s).
