1. What is Speed?

Speed is a scalar quantity that refers to how fast an object is moving, defined as the distance traveled per unit of time. It's typically measured in meters per second (m/s) in the SI system.

2. How Does the Calculator Work?

The calculator uses the basic speed formula:

Where:

• \( Distance \) — Traveled distance in meters
• \( Time \) — Time taken in seconds

Explanation: The equation shows the direct relationship between speed and distance, and the inverse relationship between speed and time.

3. Importance of Speed Calculation

Details: Calculating speed is fundamental in physics, engineering, sports science, and everyday life for understanding motion and transportation efficiency.

4. Using the Calculator

Tips: Enter distance in meters and time in seconds. Both values must be positive numbers. The calculator will compute the speed in meters per second (m/s).

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 by 3.6 (1 m/s = 3.6 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 specific moment.

Q4: Can speed be negative?
A: No, speed is always positive. Negative values would indicate direction in velocity.

Q5: What's a typical walking speed in m/s?
A: About 1.4 m/s (5 km/h) for an average adult.
