Centripetal Force Experiment
Purpose
The purpose of this experiment is to verify the accepted equation for the centripetal force of a mass during uniform circular motion. The hypothesis to be tested is that the calculated centripetal force for the stopper will be equal to the weight of the washers
Procedure
Begin this experiment by putting on safety goggles and collecting all of your materials; a tube, string, rubber stopper, tape, paper clip, washers, and a timer. Begin by measuring the mass of a washer, the rubber stopper, and a paper clip. Also measure the length of the string. Start with four washers on the mass hanger, as seen in the drawn diagram below. Practice swinging the stopper in a horizontal circular motion, holding it by the

Such as the radius, which is the length of the string, at 0.45 meters. The mass of the stopper, which is the object experiencing centripetal force, at 0.0141 kilograms. The mass of one washer at 0.0056 kilograms. Lastly the mass of one paper clip at 0.0001 kilograms. The only dependent variable in this experiment was time. Due to the varying masses on the hanger the time for ten revolutions is what determines the experimental and theoretical centripetal forces. The longest time present in this experiment was 9.25 seconds for ten revolutions with four washers on the mass hanger. The shortest time present in this experiment was 5.15 seconds for ten revolutions with 20 washers on the mass …show more content…
Such as the experimental centripetal force, which is essentially the force of gravity found by multiplying the mass of the washers and paper clip by gravity (9.8 m/s^2). The highest experimental centripetal force was 1.107 Newtons, when there was the highest amount of mass on the hanger of 0.1130 kilograms. The lowest experimental centripetal force was 0.2293 Newtons, when there was the lowest amount of mass on the hanger of 0.0234 kilograms. The time period for one revolution was also found by dividing the time for ten revolutions by 10, the highest being 0.925 seconds when four washers were on the hanger and the lowest being 0.515 seconds when 20 washers were on the hanger. The velocity of the stopper was also calculated, the fastest velocity being 5.490 meters per second when there was 20 washers on the hanger and the slowest being 3.057 meters per second. Lastly the theoretical centripetal force was calculated, the highest being 0.9444 Newtons when 20 washers were on the hanger and the lowest being 0.2928 Newtons when four washers were on the
This question can be answered by having an understanding of centripetal acceleration and centripetal force. Centripetal force described as “the force that keeps an object in its uniform circular motion.”5 The centripetal force in the Greek Waiters Tray is provided by the waiter’s arm.6 Centripetal acceleration is described as “the acceleration needed to keep an object moving in circular motion.”7 The centripetal acceleration is provided by the plate of the Greek Waiters Tray.

Our machine showed physics in many ways. It used Newtons laws, collisions, and more aspects of physics. Our project showed ten different aspects in detail. This is our machine.
Ever wonder if the weight of a Frisbee affects how far you can throw it? I have. This experiment is designed to figure out if a heavier Frisbee goes farther or closer than a lighter Frisbee.
Table 1 represents the mass of the block that was used throughout this experiment, which was found to be 0.467kg. In Table 2, the normal force and peak static frictional force were found for the wooden block alone (Table 1) and when it had 500g or 1000g of additional weight. To calculate the normal force, the weight of the block (including the weights added if applicable) was multiplied by gravity. As shown in Table 2, when no additional weight were added to the block, the normal force was 4.58N and the peak static friction was 1.775N. When 500g of weight was added to the block the normal force was 9.48N and the average peak static friction was 3.688N. Then, when 1000g was added to the block the normal force was 14.38N and the average peak static friction was 5.391N. Figure 2 demonstrates the results of the average peak static friction values vs. the normal force,
Three different size rubber bands each with their own rate of stretch when weight is added. By creating a makeshift basket, the group was able to connect a rubber band to a ring stand. After two washers were added, the group would calculate how much the washers would affect the rate of stretch of each rubber band. Multiple washers were added until the maximum amount of weights were in the basket. The shorter rubber band took more weight in order to stretch the rubber band, however the larger rubber band would not require as much force to change the rate of stretch of the rubber band. Each rubber band had its own stretch rate. The stretch of the rubber band when weight is added is affected by the length of the rubber band.
The three main forces to consider in this project were gravity, air resistance, and impact. Gravity pulled our cradle toward
After completing the experiment, the data was transferred from DataStudio to Excel file, Lab9. Next, the points in the data when it started to increase were removed from the data points because that was when the 3-step pulley spun the opposite way of its original direction. This caused the mass hangar to be pulled back up and our experiment focuses on the just the drop. After deleting the excessive data, a scatter plot was created for all five trials for both the No Ring and the Ring. Then a trendline was added for the trials and the option to show the linear equation was selected. From the graph, the angular acceleration was determined by taking the slope from the equation shown on the graph of each trial.
In the experiment these materials were used in the following ways. A piece of Veneer wood was used as the surface to pull the object over. Placed on top of this was a rectangular wood block weighing 0.148-kg (1.45 N/ 9.80 m/s/s). A string was attached to the wood block and then a loop was made at the end of the string so a Newton scale could be attached to determine the force. The block was placed on the Veneer and drug for about 0.6 m at a constant speed to determine the force needed to pull the block at a constant speed. The force was read off of the Newton scale, this was difficult because the scale was in motion pulling the object. To increase the mass weights were placed on the top of the ...
For the coffee filter paper, how does the mass, by adding items such as paper clip, affect the time for the coffee filter to fall from an initial height?
The first thing my group did was confirm our method of taking data and who would be doing it as well as defining out independent and dependent variables. Since we would be directly controlling the net force we made that our independent variable which left the acceleration as our dependent variable because it was a factor that varying as a result of our net force. We weighed our cart with every single mass in it along with the string and the hook which turned out to be 1.97kg. We did not add anything else to our system after this to keep the mass of the whole system constant. Our setup was like this: a ramp was sitting on top of the table, parallel to it so it had no slant. On one end of the ramp, a pulley was attached. On the other side of the ramp, a motion sensor was set up so it faced directly down the path of the
VII). This definition can be explained through Figure 2. In the figure, there are two bodies of the same size both with a gravitational pull, body A with center B, and body C with center D. A third body, E, is at unequal distances from centers B and D, with D being closer. Because the bodies are of the same size, but the center D is closer to E, the body E will be drawn towards body C. Accelerative quantity of centripetal force is proportional to the velocity that the force generates in a given time, and because the body E is closest to the center that is D, the accelerative quantity of centripetal force will be greater for the body C, and it will have a greater pull on body
== 1. The flywheel was set as shown with the axle of the flywheel horizontal. A polystyrene tile was placed on the floor to avoid the impact of the mass on the floor. 2. The vernier caliper was used to measure the diameter d of the axle.
