Speed Formula:
From: | To: |
Definition: This calculator determines speed when given distance and time using the fundamental relationship between these three variables.
Purpose: It helps students, teachers, and professionals solve physics and mathematics problems involving motion.
The calculator uses the formula:
Where:
Explanation: Speed is calculated by dividing the distance traveled by the time taken to cover that distance.
Details: Understanding speed calculations is fundamental in physics, transportation planning, sports science, and many engineering applications.
Tips: Enter the distance and time values in consistent units (e.g., both in miles and hours, or both in meters and seconds). All values must be > 0.
Q1: What units should I use?
A: Any consistent units work (km/h, m/s, mph), but ensure distance and time units match your desired speed unit.
Q2: Can I calculate distance or time using this formula?
A: Yes, the formula can be rearranged: \( D = S \times T \) or \( T = \frac{D}{S} \).
Q3: What if I get a very small decimal result?
A: This might indicate mismatched units (e.g., km and seconds). Convert to compatible units.
Q4: How does this relate to velocity?
A: Speed is a scalar quantity (magnitude only), while velocity is a vector (magnitude and direction).
Q5: What's the difference between average and instantaneous speed?
A: This calculator gives average speed over the entire distance and time period.
