1. What is Speed?

Speed is a scalar quantity that refers to how fast an object is moving. It is defined as the distance traveled per unit of time and is 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:

• \( Speed \) — Velocity in meters per second (m/s)
• \( Distance \) — Total distance traveled in meters (m)
• \( Time \) — Time taken to travel the distance in seconds (s)

Explanation: This fundamental physics equation calculates the rate at which an object covers distance over time.

3. Importance of Speed Calculation

Details: Speed calculation is essential in physics, engineering, sports science, transportation planning, and everyday life for understanding motion, planning travel times, and analyzing performance.

4. Using the Calculator

Tips: Enter distance in meters and time in seconds. Both values must be positive numbers greater than zero. The calculator will compute the 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: What are common units for speed?
A: Common units include m/s, km/h, mph, and knots. This calculator uses m/s as the standard SI unit.

Q3: How do I convert between different speed units?
A: To convert m/s to km/h, multiply by 3.6. To convert m/s to mph, multiply by 2.237.

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

Q5: Can this calculator handle different units?
A: This calculator uses meters and seconds. Convert other units to these before calculation for accurate results.
