Relationship between speed, distance, and time | Physics Forums
The relationship between speed, distance and time can be used to calculate any of the three variables, as long as the other two are known. The time taken for a. Speed is the rate at which distance changes over time, and you can calculate it easily -- or use it to calculate distance or time. Hi, I am having trouble understanding the relationship between speed, distance and time. For example, if time was tripled, what would be the.
Some other effect not in the list? I think you're looking too much into my question.
How to solve Time and Distance Problems using Time and Distance Formulas | TalentSprint
I don't understand what 'reynold's numbers' are. Or the time be if distance is given, but not time? I'm also wondering if the formula gets adjusted at all to compensate for a velocity limit? If the acceleration remains constant, you can't have a maximum velocity.
The velocity will just get bigger and bigger in the direction of the acceleration.

So there must be some rule about how the acceleration stops or tapers off to give that maximum velocity. Forget our remarks about Reynold's numbers etc, just let us know what's supposed to be going on physically. Is this about a ball dropped from a tower? A car driven by a law-abiding motorist? A particle in a linear accelerator? Without that information there's no way we can give an answer.
Okay, how about gravity with terminal velocity, concerning distance and time? I'm just looking for a formula, and I don't need numbers. If it helps you explain, that's fine too. I might have to use a program, or look it up somewhere, if you want that formula too. So Mathematica didn't download properly, and I had a chance to sleep on it.
For the case where the friction is proportional to velocity squared, here's what I get: You drove 45 miles in 1. At the end of your trip, your friend tells you that your average speed during the trip is 36 miles per hour. You asked yourself, 'How can a sports car have such a pitiful average speed? What is average speed anyway? The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance.
It's a scalar quantity which means it is defined only by magnitude. A related concept, average velocity, is a vector quantity. A vector quantity is defined by magnitude and direction. For example, we might say that a car has an average speed of 25 miles per hour.
Its average velocity might be 25 miles per hour due east. Average speed can be viewed as the rate of change in distance with respect to time.
A car traveling at an average speed of 25 miles per hour covers an average distance of 25 miles every hour. Calculating Average Speed If an object travels with constant speed, then the formula for the speed of the object is given by, Total distance is the distance traveled by the object at the constant speed.
Elapsed time is the time the object took to cover the total distance. In most instances, an object will travel with varying speeds over a certain distance.
For example, a car traveling from one city to another will rarely move at a constant speed. It is more likely that the car's speed will fluctuate during the trip.
The car might travel at 65 mph for some time and then slow down to 25 mph.
