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 to make that displacement.

2. How Does the Calculator Work?

The calculator uses the velocity equation:

Where:

• \( Displacement \) — Change in position (meters)
• \( Time \) — Duration of movement (seconds)

Explanation: The equation calculates how fast an object's position changes over time, including direction information.

3. Importance of Velocity Calculation

Details: Velocity is fundamental in physics for analyzing motion, calculating trajectories, and understanding dynamics in various fields from engineering to sports science.

4. Using the Calculator

Tips: Enter displacement in meters and time 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 the magnitude (scalar quantity).

Q2: What are typical velocity units?
A: Common units are meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph).

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

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

Q5: What's the velocity of light?
A: The speed of light in vacuum is approximately 299,792,458 m/s (a fundamental physical constant).
