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. In the SI system, it's measured in meters per second (m/s).

2. How Does the Calculator Work?

The calculator uses the basic speed formula:

Where:

• \( Speed \) — Measured in meters per second (m/s)
• \( Distance \) — Total distance traveled in meters
• \( Time \) — Duration of travel in seconds

Explanation: The formula 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 planning. It helps in analyzing motion and designing systems that involve movement.

4. Using the Calculator

Tips: Enter distance in meters and time in seconds. Both values must be positive numbers. The calculator will output speed in meters per second.

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 m/s by 3.6 to get km/h (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: What are typical speed measurements?
A: Walking speed is about 1.4 m/s, running ~5 m/s, cars on highway ~30 m/s (108 km/h).

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