1. What is Velocity in Physics?

Definition: Velocity is a vector quantity that refers to the rate at which an object changes its position.

Purpose: It helps in understanding motion by describing both the speed and direction of an object's movement.

2. How Does the Velocity Formula Work?

The calculator uses the formula:

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

Where:

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

3. Importance of Velocity Calculation

Details: Velocity is fundamental in physics for analyzing motion, calculating trajectories, and solving problems in mechanics.

4. Using the Calculator

Tips: Enter the distance in meters and time in seconds. Both values must be > 0. The result will be in meters per second (m/s).

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 and direction).

Q2: Can velocity be negative?
A: Yes, negative velocity indicates motion in the opposite direction of the reference point.

Q3: What units should I use?
A: The calculator uses meters and seconds, but you can convert from other units before entering values.

Q4: How is this different from average velocity?
A: This calculates average velocity over the entire distance and time period.

Q5: What if I need instantaneous velocity?
A: Instantaneous velocity requires calculus (derivative of position with respect to time).
