Speed/Velocity Formula:
| From: | To: |
The fundamental physics formula v = s/t calculates velocity (or speed) as the ratio of distance traveled to the time taken. Velocity is a vector quantity that describes both the speed and direction of motion, while speed is a scalar quantity representing only the magnitude.
The calculator uses the velocity formula:
Where:
Explanation: This formula represents the rate of change of position with respect to time, providing the average velocity over the given time interval.
Details: Velocity calculation is fundamental in physics, engineering, sports science, and transportation. It helps analyze motion, design mechanical systems, optimize athletic performance, and calculate travel times in various applications.
Tips: Enter distance in meters and time in seconds. Both values must be positive numbers greater than zero. The result will be displayed in meters per second (m/s).
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). This calculator provides the magnitude component.
Q2: Can I use different units?
A: Yes, but you must maintain consistency. If you use km for distance and hours for time, the result will be in km/h instead of m/s.
Q3: What is considered average human walking speed?
A: Typically 1.4 m/s (5 km/h), though this varies based on age, fitness level, and other factors.
Q4: How does this relate to acceleration?
A: Acceleration is the rate of change of velocity with respect to time (a = Δv/Δt). Velocity is the first derivative of position.
Q5: When is instantaneous velocity different from average velocity?
A: When an object's speed changes during motion, instantaneous velocity at any point may differ from the average velocity over the entire journey.
