1. What is the Equation for Speed?

Definition: The speed equation calculates how fast an object is moving based on the distance traveled and the time taken.

Purpose: It helps in physics, engineering, sports science, and everyday situations to determine velocity.

2. How Does the Speed Equation Work?

The calculator uses the formula:

Where:

• \( v \) — Speed (meters per second)
• \( d \) — Distance traveled (meters)
• \( t \) — Time taken (seconds)

Explanation: Speed is calculated by dividing the distance traveled by the time it took to cover that distance.

3. Importance of Speed Calculation

Details: Understanding speed is fundamental in physics, vehicle performance analysis, athletic training, and many real-world applications.

4. Using the Calculator

Tips: Enter the distance in meters and time in seconds. Both values must be > 0. The result will be 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: Can I use different units?
A: Yes, but ensure consistent units (e.g., km and hours for km/h). This calculator uses meters and seconds for m/s.

Q3: What if I have average speed and need distance or time?
A: Rearrange the formula: \( d = v \times t \) or \( t = \frac{d}{v} \).

Q4: What's a typical human walking speed?
A: About 1.4 m/s (5 km/h), but this varies by individual.

Q5: How do I convert m/s to km/h?
A: Multiply by 3.6 (1 m/s = 3.6 km/h).
