Physics Lab: Force Vectors
Purpose
To apply the laws of vector addition to resolve forces in equilibrium.

Materials
1 Force table
1 Metric ruler
1 Protractor

1 Pencil
1 Piece of Paper

Procedure
1.) Set up the apparatus, making sure the spring scales are properly calibrated at zero when no force is applied. [SEE FIGURE 1]
2.) Attach the spring scales to the force table so that each scale registers a force at approximately mid range.
3.) Place a piece of paper beneath the spring scale arrangement.
4.) Mark points along the line of action of each force.
5.) Remove the paper and use the points you marked to construct three lines (A, B, and C) originating from the center point, P.
6.) Take note of each spring scale reading
7.) Convert grams to Newton and construct vectors of properly scaled length.
8.) Add vector A to vector B, and draw the vector sum of A+B, the resultant. [SEE FIGURE 2]

Data

Data cont’d

FIGURES 2 &3

Observations & Calculations
1.) On a separate piece of paper, draw the vectors obtained from your experimental procedure. [SEE FIGURE 2]
2.) Calculate the respective velocities and velocity increases. [SEE FIGURE 2]

Analysis
What is the number scale you chose for your model?
I chose to scale my vectors with one Newton equaling one centimeter.
What is the result of the addition of vectors A and B?
It produced a vector that is in the opposite direction with the same amount

Essay on Laboratory Experiment

unknown object Theory: - The torque τ of a force F with respect to appoint O is defined as a vector whose magnitude T is given by the product T=F.d, where d is the lever arm, namely the distance between the axis of the force and point O. the condition for the rotational equilibrium of a body is that the total torque Ttot around any point is Zero. When the reference point O and all the forces of interest lie on the same plane, the torque of each force attempts to rotate the body in a clockwise or…

rise of budha Essay

empire controlling the Mediterranean Sea, which at the time of the Roman Empire, was the center of the civilized world. As years went by Rome fell. Many people link Rome and the United States together. Rome rose from nothing into a great world power, however, they reached their peak and then fell, much the same, as the United States is today. Rome and the United States are similar in many ways. Rome, at one point, was an advanced civilization that was ruled by a democracy. Also, in the beginning the…

the movement of air and other gases and of the forces involved in their movements. It is also the study of the way objects, such as cars and airplanes, interact with air when they are moving through it (The American Heritage Student Science Dictionary 6). Simply it is the study of how any objects move through the air (Brian Dunbar). Aerodynamics is a very important science. Without it, it would be nearly impossible…

Persuasive Essay On Concealed Weapons

Officers are trained to shoot at center mass. The main body of an individual. Often you hear people say that officers should shoot at the legs, but a moving person, can be hard to shoot. Shooting at the legs can lead to missed shots than can potentially strike a bystander. Shooting at the center mass has a lesser of a chance of the bullet going through the body and striking someone. Police officers also use hallow-point round. On impact, the open up. Ball-point ammo can go through multiple surfaces…

Essay on Homework 1

mathematical center thus perpetuating it without motion would contain the difficulty of making “the sharpest needle stand upright on its point upon a looking glass.” Even the minutest position off true center would place a gravitational advantage to a specific side thus putting the mass (needle) in motion. He goes further to explain that uniform distribution of galaxies in our universe would have the mathematical chances related to an infinite number of needles standing on their points on a looking…

Nicole Vargas Addition of Force Vectors Lab Mmebers: 1. Ambar Gavidia 2. Jennifer Vallejos 3. Daniela Lab Date Performance: 01/14/15 Purpose: Introduce analytical and graphical techniques for vector addition. The objective is to measure the forces acting on an object in equilibrium and calculating their vector sums. Apparatus: Four pulleys are clamped to a force table, which is graduated from 0 to 360 degrees. A central stationary object is connected by strings to three different hangers…

Figure 19: Fixation of the blue nylon inserts into the metal housing using the locator tool. Measurement of retention (vertical dislodging forces). - A universal testing machine* was used to apply and measure tensile dislodging forces. - A metal plate with four tapped opening (holes) was attached to the chains by secews. Another chains was screwed into the center of the metal plate to unite the plate with its four chains to the crosshead of the machine. (Fig20) -…

Joint Task Force-Iraq

In 2014 when Canada deployed a Task Force to fight the war against the Islamic State of Iraq and Syria (ISIS), the Canadian Armed Forces (CAF) became involved in the Coalition targeting process. Targeting is enabled by intelligence and works best when operations and intelligence are highly integrated. Collection planning to support target development is executed by operation staff, so the closer the link and understanding between intelligence and operations the more coherent the results. Further…

Essay on Astronomy: Moon and Sun

Astronomy 1) Our ancestors used to look up at the sky and see the same view as we do today. History shows that humans used to think that we (the earth) were the center on the universe. From earth it appears that the stars, planets, and the sun are revolving around us each day. We used to think we were located at the center because the fact that we cannot feel the constant motion as the earth rotates on its axis and orbits around the sun. This is an ancient idea called geocentric and as time…
