1. What is Velocity?

Velocity is a physical vector quantity that measures the rate of change of displacement with respect to time. It describes both the speed and direction of motion of an object.

2. How Does the Calculator Work?

The calculator uses the velocity equation:

Where:

• \( v \) — Velocity (m/s)
• \( d \) — Distance traveled (meters)
• \( t \) — Time taken (seconds)

Explanation: The equation calculates how fast an object is moving by dividing the distance covered by the time taken to cover that distance.

3. Importance of Velocity Calculation

Details: Velocity is fundamental in physics and engineering for analyzing motion, designing transportation systems, calculating kinetic energy, and solving problems in mechanics.

4. Using the Calculator

Tips: Enter distance in meters and time in seconds. Both values must be positive numbers. The calculator will compute velocity in meters per second (m/s).

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 (both magnitude and direction).

Q2: What are typical velocity units?
A: Common units include m/s (SI units), km/h, mph, and ft/s. This calculator uses m/s.

Q3: Can velocity be negative?
A: Yes, negative velocity indicates motion in the opposite direction of the reference frame.

Q4: How does this relate to acceleration?
A: Acceleration is the rate of change of velocity with respect to time (a = Δv/Δt).

Q5: What's instantaneous velocity?
A: The velocity at a specific instant in time, as opposed to average velocity over a time interval.
