The question on hand was whether or not the acceleration was the same going uphill as it was downhill or different from each other in both directions. To obtain a secure conclusion this experiment required the use of a frictionless cart, an inclined ramp, motion sensor, meter stick, and assistance of computer programs. These tools help us to achieve/correct our predictions by giving us precise information about the acceleration of the cart in both the up and downhill direction.
Prediction:My prediction for Problem # 5 was how I felt that the acceleration of the cart would be equal but opposite to each other on the way up and down. As the cart is going uphill it would have a negative acceleration (see notebook for rough sketch of graph) because its slowing down and eventually going to return back to the bottom. As the cart is going down hill it is working with the acceleration making acceleration positive in a quantitative sense.
Data & Results:The lab for Problem #5 was conducted in a pretty simple manner. Since are main goal was to see if acceleration were the same on the way up as it was down we just had to do a couple experimental runs by launching the cart up the hill, allowing it to reach its max distance up and then come back down. While doing the previous mentioned we recorded with the motion sensor the distance versus time, velocity versus time, and acceleration versus time. Instead of going with the acceleration versus time graph that the computer was able to give us, I made my own points of data using the velocity versus time graph by using its slope in between points to calculate the acceleration at each point. After calculating the slope between points I took that average and compared it to what the computer gave us for a line of best fit and my calculation came out to be -1.192 m/s2 and
the computers calculation was -1.22 m/s2. This in a way corresponds to what my prediction was but instead in my prediction I said it would be a different sign, as in positive (uphill) or negative (downhill), not thinking that acceleration is the same both ways.
Uncertainty for this lab arises when discussing the exact measurements for the ramp and as well as the angle for which the ramp was held. This is due to the precision to which the measurement was taken, which leaves about a ±.1 cm as uncertainty for the recorded sides. To get the most accurate results possible each measurement was taken a bunch of times and the number that was most frequently recorded was used. There is also some uncertainty in the validity of the velocity and acceleration documented by the LabVIEW program. This is because it is impossible to be exactly in unison to allow the program to begin measuring the acceleration and velocity over time and releasing the cart down the inclined plane.
Api. With this code the LabVIEW will not have to take into account the fact that some of the components with angular momentum (like the accelerometer) won’t be connected to the ground directly with the Cartesian plane. Instead, it will just follow the same procedure. A second example has been made using the Pi tool. In it you can make out the axis that is perpendicular to the angular plane while keeping the two axes separate at all times. The Cartesian plane is not at any degree of a true diagonal because the coordinate of the two axes is different. So all you have to do is move the Cartesian from its correct point on the line to the part where the Cartesian is. In other words, if the Cartesian is pointing directly at the axis in the above example you can’t move the cart at all. The Cartesian is actually pointing directly at the center of the point in your project and that points to the true plane, and that point is not being in the Cartesian at all. However, if you are trying to get an exact velocity at a specified velocity, you can probably figure out what this gives you in the first place. A closer look at the code to get an idea of these differences. A second example using pi, a more accurate vector vector printer, can also be found as well. The Pi version shows the coordinates of the Cartesian axis; these are also known as the Cartesian axes. In previous versions also there was no point-distributing coordinate, so they were used only along the horizontal line to avoid having to refer to any diagonal values. But since I believe the same principle applies to vectors (for any given value of a variable or method of reference) I used it again as an additional means of getting more complete values. A bit more information comes by way of a short description on the Pi. The Pi is also supported by the A3-L printer; both the Cartesian and the Cartesian axes are shown above, along with a video showing an implementation of the Pi.
