1. What is Speed?

Speed is a scalar quantity that measures how fast an object is moving. It is defined as the distance traveled per unit of time and is typically measured in meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph).

2. How Does the Calculator Work?

The calculator uses the basic speed formula:

Where:

• \( v \) — Speed (m/s)
• \( d \) — Distance traveled (meters)
• \( t \) — Time taken (seconds)

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 determining travel times, vehicle performance, and motion analysis.

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 automatically 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 typical speed units?
A: Common units include m/s, km/h, mph, ft/s. This calculator uses meters per second (m/s).

Q3: Can I use different units?
A: Yes, but ensure consistency. If using km and hours, speed will be in km/h using the same formula.

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

Q5: How does this relate to acceleration?
A: Acceleration is the rate of change of velocity over time, while speed is the magnitude of velocity.
