Rate of Speed Calculator
Understanding how to calculate the rate of speed is fundamental in physics and everyday life. Speed is a measure of how quickly an object is moving. It is defined as the distance traveled per unit of time.
How to Calculate Rate of Speed
The formula for calculating the rate of speed is straightforward:
Speed = Distance / Time
Where:
- Speed is the rate at which an object covers distance. Its common units are meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph).
- Distance is the total length covered by an object during its movement.
- Time is the duration over which the movement occurred.
To use the calculator above, simply input the total distance your object traveled and the time it took to cover that distance. The calculator will then compute the average speed.
Example Calculation:
Imagine a runner completes a 200-meter race in 25 seconds.
- Distance = 200 meters
- Time = 25 seconds
Using the formula: Speed = 200 meters / 25 seconds = 8 meters per second (m/s).
The runner's average speed was 8 m/s.
function calculateSpeed() {
var distanceInput = document.getElementById("distance");
var timeInput = document.getElementById("time");
var resultDiv = document.getElementById("result");
var distance = parseFloat(distanceInput.value);
var time = parseFloat(timeInput.value);
if (isNaN(distance) || isNaN(time)) {
resultDiv.innerHTML = "Please enter valid numbers for distance and time.";
return;
}
if (time <= 0) {
resultDiv.innerHTML = "Time taken must be greater than zero.";
return;
}
var speed = distance / time;
resultDiv.innerHTML = "
Your Calculated Speed:
" +
"" + speed.toFixed(2) + " meters per second (m/s)";
