1. What is Speed?

Speed is a measure of how fast an object is moving. It is defined as the distance traveled per unit of time. The SI unit for speed is meters per second (m/s).

2. How Does the Calculator Work?

The calculator uses the speed formula:

Where:

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

Explanation: The equation calculates how many meters an object travels each second.

3. Importance of Speed Calculation

Details: Calculating speed is fundamental in physics, engineering, sports science, and transportation. It helps in understanding motion and performance.

4. Using the Calculator

Tips: Enter distance in meters and time in seconds. All 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: How do I convert m/s to km/h?
A: Multiply the speed in m/s by 3.6 to get km/h.

Q3: What is average speed vs instantaneous speed?
A: Average speed is total distance over total time, while instantaneous speed is the speed at a particular moment.

Q4: What are typical speed measurements?
A: Walking speed is about 1.4 m/s, running speed 3-5 m/s, car speed 13-30 m/s (50-110 km/h).

Q5: Can speed be negative?
A: No, speed is always positive. Velocity can be negative to indicate direction.
