The purpose of this experiment is determine the resultant of several concurrent coplanar forces though the use of graphical addition, rectangular components by graphical and trigonometric methods, and the use of the a force table. The magnitude through trigonometric methods was 1212.4 newtons,and the the magnitude through graphical addition was 1184 newtons. Due to time constraints, we were not able to use the force table.

Discussion In part A, the weight of each force is found by multiplying the mass(g) of each force by gravity(10.0 m/s^2). The weight of force one is calculated using the mass, 55.0 grams, by gravity to give a weight of 550 Newtons. A potential source of error in this step of the experiment may come from rounding the acceleration due to gravity from 9.8 m/s^2 to 10.0 m/s^2. This will leading to slightly higher values of weight for each of the forces. Using trigonometric methods to calculate the resultant is the focus of part B. After a sketch of the problem is drawn, we calculated the X- and Y-components of each vector using Eq. (1): F(x)=FCos훉. The X-component of each force is 275N, -375 N, and -350N, respectively. The Y-component of each force is 475N, 650N, and 0N. The negative sign indicates that the vector was drawn either to the left of the y-axis, or below the x-axis. We than added the all the X-components together and all the Y-components together. The X-component of the resultant is -450 newtons and the Y-component 1126 newtons. Next,

To begin the experiment, we measured the masses of the two stoppers and the eye bolt used to secure the stoppers that we were using in our apparatus. The mass of the first stopper was 18.8 grams and the mass of the second stopper was 50.5 grams. The mass of the eye bolt was 11.6 grams. The mass of the screw and bolt that secured our hanging mass was given to us as 25 grams. After, we chose six different hanging masses based on stopper mass. We made sure that the hanging mass was always larger than the stopper mass or else we would not be able to get the stopper to spin at a constant velocity. The first three mass ratios we chose was using the stopper with the mass of 18.8 grams and then we used a hanging mass (the mass of the screw and bolt is included) of 65 grams, 85 grams, and 105 grams. This gave the three mass

First, we will set up the force table. The table comes in three separate pieces the base, stand and table once we connect and fasten all three parts we must use a circular level to make sure the table is balanced. If the force table isn’t balanced then we must adjust the base’s feet to the appropriate levels on each leg till the bubble on the level is centered. We must then assign where the positive & negative x, y axis are on the force table as a point of reference and label them with tape .Then for part I we must apply 1.96 N in the positive x – direction, and 2.94 N in the positive y-direction then we must balance the two with a third force and record the magnitude and direction of it and a draw a diagram showing all three forces.

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.

## Comparing The Spring Constant And The Velocity Of A Duck

- 1424 Words
- 6 Pages

To do the first experiment, the work-energy theorem is used. This is based on the equation .5mv^2=.5kx^2, where m is the mass of the duck, v is the velocity of the duck in the air, k is the spring constant of the spring in the base of the duck, and x is the displacement that the spring is compressed. Place a book on top of the .95m table. This will serve as a backstop for launching the duck. Then push the duck so it is compressed and is going to launch horizontally . Do this a few times to find an approximate horizontal distance from the base of the table to where the duck initially contacts the ground. One you have found this distance, focus more carefully on this position so that you can take a measurement from the edge of the table to the position where the duck initially contacted the ground. This allows you to get a more accurate answer. Do this at least five times and take the average. Then you can change the height of by adding a .75m desk on top of the .95m table. Repeat the process of data collection at least 5 times and take the average. Then remove the .75m desk and place it on the ground. The desk will then be used to launch from a vertical displacement of .75m place the duck up against the book and launch it horizontally, again collecting 5 separate data points and taking the average of the

## The Measurement Of Pendulum 's Harmonic Motion Lab Essay

The specific purpose of this experiment was to verify three physical concepts based on Newton’s Laws. These concepts are vector addition, force as a vector, and the law of equilibrium. The densities of two different objects were compared by measuring their masses and volumes. In this experiment, two different sets of methods of volume measurement were compared to the density computation of an object bearing a standard shape. In addition, the density computation was used to determine the buoyant force acting on different objects. At this point, it was observed that an object maintains a constant velocity if all the external forces cancel out one another (no net force results from the unbalanced forces acting on an object). In this case, a force table was used to study Newton’s First Law of Motion. These forces were represented as F1, F2, and F3. Analysis of results obtained from the experiment proved that the value of F3 determined through calculations was less than the measured value of F3. In Trial#1, for example, the calculated value of F3 was 211.59g @ 2430 while the measured value of F3 was 215g @2430, translating to a % difference of 0.5g @20. Although the primary objectives of the lab were achieved, errors (in particular, static friction) occurred during the experiment. These errors were observed
