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 equation:

Where:

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

Explanation: The equation shows that velocity is directly proportional to distance and inversely proportional to time.

3. Importance of Velocity Calculation

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

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: Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

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 does this differ from acceleration?
A: Acceleration is the rate of change of velocity over time (m/s²).

Q5: What's instantaneous velocity?
A: The velocity of an object at a specific instant in time, as opposed to average velocity over a period.
