Drag Coefficient Lab Report

This data was tested using a pound of soft, polymer clay, a small Jolly Rancher candy, ruler, pencil, and a measuring tape. The Jolly Rancher weighed 6 grams. The pencil was placed underneath the middle of the ruler for balance. On one end, I placed the Jolly Rancher and dropped the clay on the other end. I started dropping the clay from 107 centimeters. The measuring tape was placed behind the pencil and ruler. I then video-taped the event to pinpoint the exact launch height of the candy. The first experiment had no force

This was due to the formulas used to calculate the actual velocity and acceleration: 2πr/t for speed and v2/r for acceleration. As for the other forces identified within the lab, the force of air resistance equaled the net force and allowed the flying cow to travel at a constant velocity.

1) Once the simulation opens, click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around.

In Lab 6, we will exploring the conversation of mechanical energy. In this experiment we will be using various tools and instruments of measurement such as an air track, a glider, a photogate and an interface box. Because we are creating an isolated system, the total mechanical energy is conserved where gravitational kinetic energy is transferred to kinetic energy. In this experiment we can see the conservation of energy when the glider on the air track is pulled by the force of gravity acting upon the weight of the falling mass. We are able to neglect friction due to the presence of the air cushion which reduces the friction acting on the glider.

We used this measured Mach number

Many things can’t be explained, but I have explained a few things that might seem confusing. If distance equals rate times time, than how fast the object is going, and how long the object is staying in the air is key. The machine that works faster and keeps the object in the air longer should be better than the other. Unless there is a difference in the objects, as such as one might be lighter, or float to stay in the air longer. Or if one object is more aerodynamic than the other.

Copied the observations table in our notebook. Then recorded the mass of the beaker using the balance and wrote down the measured mass in the observation

For example, when the car had 3 weights on it and weighed 1,457.9 grams, the average acceleration was 0.4116 m/s². When the car did not have any weights on it and weighed 653.7 grams, the average acceleration was 0.8771 m/s², which is more than double the acceleration of the car had 3 weights on it. When an extra 804.2 grams of weight was added to the car, the acceleration decreased by 0.4655 m/s². The evidence provided by the experiment proves that the more mass the object has, the more the acceleration will decrease, showing the direct relation between both mass and acceleration.

Purpose: The purpose of the practical is to find how mass affects acceleration and how it affects also the force of the accelerating body. To do this we are going to do the ticker tape experiment where an accelerating body pulls a tape through a consistent 50 dot per second ticker timer. The acceleration body in this experiment will be a small trolley pulled by a string that is pulled by the downfall of different masses which will then tell how mass affects acceleration.

* The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance, hang time, speed, and many other factors. Understanding the models I have chosen to make help me

4. Prepare a vacuum filtration apparatus using a buchner funnel. Obtain one filter paper for each one of your samples, weigh them and record their mass in your notebook (label them with a pencil to be able to differentiate them later).

An uncertainity of 0.001g was appropriate for the mass measurements

HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction.

In the first part of the experiment, the fundamental quantities-length, mass and time were estimated simply by guessing. Even though it can be helpful sometimes to test a hypothesis, huge percentage errors in the measurements showed that human errors can be significant and therefore, we need more sophisticated techniques for more accurate measurement. For instance, using Vernier calipers is more precise than guessing the length or more accurate than the ruler.
