### Relationship between Speed, Distance and Time | Uniform Speed | Variable speed

The formulas for speed, distance and time are all examples of mathematical The relationship between distance, speed and time can serve as the basis for. As long as the speed is constant or average, the relationship between speed, distance, and time is expressed in this equation. Speed=DistanceTime, Speed. Speed is a measure of how quickly an object moves from one place to another. It is equal to the distance traveled divided by the time. It is possible to find any of.

Often these problems require calculating the relative motions of trains, planes and automobiles. These equations can also be applied to more complex problems like the speeds of sound and light, the velocity of planetary objects and the acceleration of rockets. Average velocity equals speed in a direction.

Formula for Speed Speed refers to distance traveled during a period of time. The commonly used formula for speed calculates average speed rather than instantaneous speed. The average speed calculation shows the average speed of the entire journey, but instantaneous speed shows the speed at any given moment of the journey.

A vehicle's speedometer shows instantaneous speed.

Average speed can be found using the total distance travelled, usually abbreviated as d, divided by the total time required to travel that distance, usually abbreviated as t. Sciencing Video Vault Instantaneous speed actually is a velocity calculation that will be discussed in the velocity section. Units of speed show length or distance over time. Formula for Velocity Velocity is a vector value, meaning that velocity includes direction.

Velocity equals distance traveled divided by time of travel the speed plus the direction of travel. For example, the velocity of a train traveling 1, kilometers eastward from San Francisco in 12 hours would be 1, km divided by 12 hr east, or kph east. Your first point should be at 0,20 cm because you are going to give it a cm head start. Your second point for the slow car is the velocity you measured. The X value should be whatever time it took for the car to reach the end of your test course, your Y value is the distance you had the car travel 1.

Using your ruler and pencil, connect the two points to make a line. Now, plot the velocity of the faster car. Your first point should be at 0,0 cm because this car will not get a head start. Your second point for the fast car is the velocity you measured. Using your ruler and pencil connect the two points to make another line.

Make this line look different than the first, either by making dashes or making it darker. Label the lines fast car and slow car. Find where the two lines cross. At this intersection point, trace one line to X axis, and another to the Y axis.

These are the lines with arrows on diagram 1. The two values you see are the time and distance where the fast car should overtake the slower car. Mark the predicting passing point on your course. The distinction is as follows. Instantaneous Speed - the speed at any given instant in time.

You might think of the instantaneous speed as the speed that the speedometer reads at any given instant in time and the average speed as the average of all the speedometer readings during the course of the trip. Moving objects don't always travel with erratic and changing speeds. Occasionally, an object will move at a steady rate with a constant speed.

That is, the object will cover the same distance every regular interval of time. If her speed is constant, then the distance traveled every second is the same.

The runner would cover a distance of 6 meters every second. If we could measure her position distance from an arbitrary starting point each second, then we would note that the position would be changing by 6 meters each second.

This would be in stark contrast to an object that is changing its speed. An object with a changing speed would be moving a different distance each second.

The data tables below depict objects with constant and changing speed. Now let's consider the motion of that physics teacher again. The physics teacher walks 4 meters East, 2 meters South, 4 meters West, and finally 2 meters North. The entire motion lasted for 24 seconds.

## Distance Speed Time Formula

Determine the average speed and the average velocity. The physics teacher walked a distance of 12 meters in 24 seconds; thus, her average speed was 0. Remember that the displacement refers to the change in position and the velocity is based upon this position change.

Here is another example similar to what was seen before in the discussion of distance and displacement. The diagram below shows the position of a cross-country skier at various times. At each of the indicated times, the skier turns around and reverses the direction of travel.
