1. What is Velocity?

Velocity is a vector quantity that refers to the rate at which an object changes its position. It includes both the speed of an object and the direction of its motion. In physics, velocity is typically measured in meters per second (m/s).

2. How Does the Calculator Work?

The calculator uses the basic velocity formula:

Where:

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

Explanation: The formula calculates how much distance is covered per unit of time, giving the speed and direction of motion.

3. Importance of Velocity Calculation

Details: Velocity is fundamental in physics for understanding motion, calculating kinetic energy, determining momentum, and solving problems in mechanics and engineering.

4. Using the Calculator

Tips: Enter distance in meters and time in seconds. Both values must be positive numbers (distance > 0, time > 0).

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

Q3: What are typical velocity units?
A: Common units include m/s (SI units), km/h, mph, and ft/s. This calculator uses m/s.

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 about instantaneous vs average velocity?
A: This calculator gives average velocity. Instantaneous velocity would require calculus (limit as Δt approaches 0).
