1. What is the Speed/Velocity Equation?

Definition: This calculator computes velocity (or speed) using the basic physics equation that relates distance and time.

Purpose: It helps students, physicists, and engineers determine how fast an object is moving based on the distance traveled and time taken.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ v = \frac{d}{t} \]

Where:

Explanation: Velocity is calculated by dividing the distance an object travels by the time it takes to cover that distance.

3. Importance of Velocity Calculation

Details: Understanding velocity is fundamental in physics, engineering, transportation planning, sports science, and many other fields.

4. Using the Calculator

Tips: Enter the distance in meters and time in seconds. Both values must be positive, with time > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between speed and velocity?
A: Speed is scalar (magnitude only), while velocity is vector (magnitude + direction).

Q2: Can I use different units?
A: Yes, but ensure consistent units (e.g., km and hours, or miles and hours) and convert the result appropriately.

Q3: What if I get a negative time value?
A: Time must always be positive. Negative time values are not physically meaningful in this context.

Q4: How accurate is this calculation?
A: It gives average velocity. For instantaneous velocity, calculus (derivatives) is needed.

Q5: What about acceleration?
A: This calculates constant velocity. For changing velocity, use \( v = u + at \) where u is initial velocity and a is acceleration.
