1. What is the Speed Formula?

Definition: The speed formula calculates how fast an object is moving by dividing the distance traveled by the time taken.

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

2. How Does the Speed Calculator Work?

The calculator uses the formula:

\[ S = \frac{D}{T} \]

Where:

Explanation: The distance covered is divided by the time taken to cover that distance, giving the average speed.

3. Importance of Speed Calculation

Details: Speed calculations are 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 calculator will compute speed in meters per second.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for distance and time?
A: The calculator uses meters for distance and seconds for time by default, resulting in m/s. You can convert other units to these before input.

Q2: How do I calculate speed in km/h?
A: Multiply the m/s result by 3.6 (or use km for distance and hours for time in the formula).

Q3: What if I have zero time?
A: Time cannot be zero in the denominator - this would represent infinite speed which is physically impossible.

Q4: Does this calculate average or instantaneous speed?
A: This calculates average speed over the given distance and time period.

Q5: Can I use this for velocity calculations?
A: Speed is a scalar quantity (magnitude only), while velocity is a vector (magnitude and direction). This calculates speed only.
