Velocity and distance relationship

What is the relationship between velocity and distance? | Socratic

velocity and distance relationship

In distance-speed relations, we will learn about the Distance formula. We will also see velocity we will see many examples from this section, we will. When you do not know the time, but have the velocity and distance, AND you know it is undergoing constant accelleration you can use the formula d = 1/2. Here's a word equation that expresses the relationship between distance, velocity and time: Velocity equals distance travelled divided by the time it takes to get.

Displacement and Velocity

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.

Mark off the calculated point where the faster car should overtake the slower car. Have your assistant release the slower car at the head start mark while you simultaneously release your faster car at the starting line.

Start the timer a third person might be nice for this. Watch carefully to see where the fast car overtakes the slow car. Compare your predicted time and distance that the fast car overtook the slower car with the actual values.

Results Your results are likely to be pretty close to what your graph predicts, but they will likely vary depending on the velocities of your cars and whether or not they travel at a consistent velocity. Conduct more trials if you wish. Uniform velocity is a linear function, making them easy and fun to predict.

Although the slower car had a head start in distance, the faster car covered more distance in less time, so it caught up. This is where the lines crossed.

A non-graphical way of looking at this is using the following equation: The total distance each car travels to intersect is the same. Then, you can tell your parents how soon you will arrive at your destination. The answer given to this question is incorrect. The original answer apparently assumed that the velocity you knew was only the initial one. In that case that answer is correct as stands. You seem to assume we know both the initial and final velocities.

So of course if you know two velocities you know more than if you just know one. In the formula for distance: How do you calculate for distance then? You'll have to specify this a little more before we can answer.

Is there constant acceleration until that velocity is reached, then the acceleration stops? If so, I bet you could solve it yourself.

Or is there, more plausibly, one of these other situations which also lead to limiting velocities: This applies to objects whose terminal velocities correspond to small Reynold's numbers. This applies to objects whose terminal velocities correspond to larger Reynold's numbers, including typical large falling objects.

Some other effect not in the list?

Distance, Velocity, and Acceleration

I think you're looking too much into my question. 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.
