1. What is the Speed Equation?

Definition: This calculator computes speed using the fundamental physics equation that relates distance traveled to time taken.

Purpose: It helps students, physicists, and engineers calculate speed when distance and time are known.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Speed Calculation

Details: Understanding speed is fundamental in physics, engineering, transportation planning, and many real-world applications like vehicle speed measurement and athletic performance analysis.

4. Using the Calculator

Tips: Enter the distance in meters and time in seconds. Both values must be greater than 0.

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: The calculator uses meters and seconds for SI units. For other units, convert to meters and seconds first.

Q3: What if I get zero or negative values?
A: Both distance and time must be positive numbers greater than zero.

Q4: How precise are the results?
A: Results are displayed to 3 decimal places for most practical applications.

Q5: What about average vs instantaneous speed?
A: This calculator gives average speed over the entire distance and time period.
