Speed Formula:
From: | To: |
Speed is a scalar quantity that refers to how fast an object is moving. It is defined as the distance traveled per unit of time and is typically measured in meters per second (m/s) in the SI system.
The calculator uses the fundamental speed formula:
Where:
Explanation: This formula calculates the average speed over a given distance and time period. It represents the constant speed that would cover the same distance in the same amount of time.
Details: Calculating speed is essential in physics, engineering, sports science, and everyday life. It helps in understanding motion, planning travel times, analyzing vehicle performance, and ensuring safety in transportation systems.
Tips: Enter distance in meters and time in seconds. Both values must be positive numbers greater than zero. The calculator will compute the average speed in meters per second.
Q1: What is the difference between speed and velocity?
A: Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction). Speed tells you how fast, velocity tells you how fast and in what direction.
Q2: What are typical speed units?
A: Common units include meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), and feet per second (ft/s).
Q3: How do I convert m/s to km/h?
A: Multiply the speed in m/s by 3.6 to get km/h. For example, 10 m/s = 36 km/h.
Q4: What is average speed vs instantaneous speed?
A: Average speed is total distance divided by total time. Instantaneous speed is the speed at a specific moment in time.
Q5: Can this calculator be used for any moving object?
A: Yes, this formula works for any object moving at constant speed or for calculating average speed over a distance.
