Distance, Velocity, and Acceleration
Learn about and revise motion in a straight line, acceleration and motion the distance travelled, measured in a straight line from start to finish; the direction of the straight line The change in velocity can be calculated using the equation. We next recall a general principle that will later be applied to distance-velocity- acceleration problems, among other things. If F(u) is an anti-derivative of f(u), then. There is a relationship between distance, velocity and acceleration. When you understand how they interact, and their equations they become.
The Relationship Between Velocity and Acceleration. by Katie Crocker on Prezi
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? I think you're looking too much into my question. I don't understand what 'reynold's numbers' are.
Relationship between time, displacement, velocity, acceleration. Kinematic.
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. Remember— centimeters is the same as 1.
Plot the velocity of the slower car. 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. 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.
