1. What is the Speed Formula in Physics?

Definition: This calculator computes the speed of an object using the basic physics formula for speed.

Purpose: It helps students and professionals determine the speed of an object given its displacement and time interval.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( v \) — Speed (meters per second)
• \( \Delta x \) — Displacement (meters)
• \( \Delta t \) — Time interval (seconds)

Explanation: The displacement is divided by the time interval to calculate the average speed.

3. Importance of Speed Calculation

Details: Calculating speed is fundamental in physics for understanding motion, analyzing forces, and solving kinematics problems.

4. Using the Calculator

Tips: Enter the displacement in meters and time interval in seconds. Both values must be positive numbers.

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 this calculate instantaneous speed?
A: No, this calculates average speed over the given time interval.

Q3: What units should I use?
A: The calculator uses meters for displacement and seconds for time, resulting in m/s for speed.

Q4: What if the time interval is zero?
A: Time cannot be zero (division by zero is undefined). The calculator requires time > 0.

Q5: How is this different from the distance formula?
A: This uses displacement (change in position), not total distance traveled.
