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, and includes both magnitude and direction.

2. How Does the Calculator Work?

The calculator uses the velocity formula:

Where:

• \( v \) — Velocity (m/s)
• \( x_f \) — Final position (m)
• \( x_i \) — Initial position (m)
• \( t \) — Time interval (s)

Explanation: The formula calculates the average velocity over a given time interval by determining the displacement (change in position) divided by the time taken.

3. Importance of Velocity Calculation

Details: Velocity calculation is fundamental in physics and engineering for analyzing motion, predicting future positions, and understanding the dynamics of moving objects in various applications from vehicle design to sports science.

4. Using the Calculator

Tips: Enter final position and initial position in meters, and time in seconds. Time must be greater than zero. All values should be accurate measurements for precise results.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between velocity and speed?
A: Velocity is a vector quantity that includes direction, while speed is a scalar quantity that only measures magnitude without direction.

Q2: Can velocity be negative?
A: Yes, negative velocity indicates motion in the opposite direction of the chosen positive reference direction.

Q3: What are typical velocity units?
A: The SI unit is meters per second (m/s), but other common units include kilometers per hour (km/h) and miles per hour (mph).

Q4: Does this calculator give average or instantaneous velocity?
A: This calculator provides average velocity over the specified time interval.

Q5: When is this formula not applicable?
A: This formula assumes constant velocity. For objects with changing velocity, instantaneous velocity or more complex calculations are needed.
