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 formula:

Where:

• \( Distance \) — Traveled distance in meters
• \( Time \) — Time taken in seconds

Explanation: The formula 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 various natural phenomena.

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 that only measures how fast an object is moving.

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

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

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

Q5: What's escape velocity?
A: The minimum speed needed for an object to escape a planet's gravitational pull without further propulsion.
