1. What is Velocity?

Velocity is a vector quantity that refers to the rate at which an object changes its position. It is defined as the displacement of an object divided by the time taken. In simpler terms, it's speed with direction.

2. How Does the Calculator Work?

The calculator uses the velocity formula:

Where:

• \( v \) — Velocity (m/s)
• \( d \) — Distance traveled (meters)
• \( t \) — Time taken (seconds)

Explanation: The formula calculates how fast an object is moving by dividing the distance it covers by the time it takes to cover that distance.

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.

4. Using the Calculator

Tips: Enter distance in meters and time in seconds. Both values must be positive numbers. The result will be 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: What are common units for velocity?
A: Common units include meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph).

Q3: Can velocity be negative?
A: Yes, negative velocity indicates motion in the opposite direction of the reference point.

Q4: How is average velocity different from instantaneous velocity?
A: Average velocity is total displacement over total time, while instantaneous velocity is velocity at a specific moment.

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).
