1. What is Velocity?

Velocity is a physical vector quantity that refers to "the rate at which an object changes its position." It is measured in meters per second (m/s) in the SI system.

2. How Does the Calculator Work?

The calculator uses the velocity equation:

Where:

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

Explanation: The equation calculates how fast an object is moving by dividing the distance traveled by the time taken to cover that distance.

3. Importance of Velocity Calculation

Details: Velocity is fundamental in physics and engineering for analyzing motion, designing transportation systems, and understanding mechanical systems.

4. Using the Calculator

Tips: Enter distance in meters and time in seconds. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between speed and velocity?
A: Velocity includes both speed and direction, making it a vector quantity, while speed is a scalar quantity.

Q2: What are typical velocity units?
A: The SI unit is m/s, but km/h and mph are also commonly used in different contexts.

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

Q4: How is instantaneous velocity different?
A: Instantaneous velocity is the velocity at a specific instant, while average velocity is over a time period.

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).
