1. What is Speed?

Speed is a scalar quantity that refers to "how fast an object is moving." It is the rate at which an object covers distance. The average speed is the distance traveled divided by the time taken.

2. How Does the Calculator Work?

The calculator uses the speed formula:

Where:

• \( Distance \) — Distance traveled (meters)
• \( Time \) — Time taken to travel (seconds)

Explanation: The formula calculates how much distance is covered per unit of time.

3. Importance of Speed Calculation

Details: Calculating speed is fundamental in physics, engineering, sports science, and everyday life. It helps in determining how quickly objects move from one point to another.

4. Using the Calculator

Tips: Enter distance in meters and time in seconds. All values must be valid (distance > 0, time > 0).

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 common units for speed?
A: Common units include meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph).

Q3: How do I convert between different speed units?
A: To convert m/s to km/h, multiply by 3.6. To convert km/h to m/s, divide by 3.6.

Q4: What is instantaneous speed vs average speed?
A: Instantaneous speed is the speed at a specific moment, while average speed is the total distance divided by total time.

Q5: Can speed be negative?
A: No, speed is always a positive value or zero. Velocity can be negative when indicating direction.
