Recommended: Centrifugal Force Experiment
Theory Centripetal force is a force that makes and object move in a circular path. When an object moves in a circle it can have a constant speed where the magnitude of the velocity is the same but the direction is always changing so the velocity cannot be considered constant. For the velocity to change there must be an acceleration and from there on we can calculate the centripetal force. There are also instances where we don’t know the velocity but we know the time it takes to so from that we can get the velocity of the object that is traveling in the circle. Then by using the laws of conservation of energy we can figure out the height a ball must be dropped from to over come the force of gravity so it can make it around the loop.

First we took the cart off the mass and weighed it obtaining a value of .05kg. Then we attached the cart back to the apparatus and added a 100g mass to it making the total mass of the cart .15kg. Then we adjusted the radius between the cart and center of the apparatus to be .09m. When the cart was finally set up properly we made sure that loggerpro was synched and began to spin the apparatus by hand. The results were recorded in loggerpro over a span of about four seconds and the data was recorded. We then picked three angular velocities off of the plot, and decided to use the values 14.83 rad/s, 15.15 rad/s, and 16.07 rad/s. these values would then be used to calculate the centripetal force by plugging them into the formula F=mV^2/R. After all of the values were plugged in the centripetal force was calculated and those value were 2.94N, 3.10N, and 3.49N. They were then compared with the measured values of centripetal force and those values were 2.47N, 2.65N, and 2.83N. These values do not quite matchup so we also took the percent error for each of the values and obtained errors of -.19, -.17,-.23. One reason why we may not of been able to get the same results as the calculated values is that we did not take into account any kind of friction that the apparatus may have been experiencing while being spun …show more content…
The apparatus was spun around and the angular velocities measured were 10.47rad/s, 14.40 rad/s, and 15.76 rad/s. Then using those values and the equation F=mV^2/R we calculated the centripetal force one more time and the values were 4.39N, 8.29N, and 9.94N. Those results were compared with the measured results, which were 3.44N, 7.15N, and 8.41N. Since these values did not matchup perfectly with the calculated value we found the percent error and those values were -.28, -.16, and -.18. Then we took and average of all nine percent errors that were obtained and a value of -.17. This number wouldn’t be considered the best number but its not too bad. Reasons of what could of caused the error to be a little high can be due to factors such as friction and air
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.
There were no significant error factors that may have affected the arrangement of the lab experiment. Everything went smoothly with relative ease.
Discussion: The percent of errors is 59.62%. Several errors could have happened during the experiment. Weak techniques may occur.
The use of force is a heated topic among many people. What is the “Use of Force Continuum”? It is the level of force an officer can use when arresting or subduing a suspect. According to Hicks (2004), “It is considered morally reprehensible for an officer or a sovereign agent to use excessive force without due necessity. However, once the need arises for a proper escalation of force, both the doctrinal theses of just war and the use of force continuum provide for a proper and morally principled use of necessary force” (pg. 255). The use of force continuum was created to guide officers so they are less likely to use excessive force. The officer is expected to use more force than the suspect, but no so that it is deemed excessive. According to Lyman
The hypothesis is that the ideal and experimental values for vB should be approximately the same, as the initial velocity of the marble falling off the ramp and off the lab bench should be the same, as long as no additional forces are applied. Although, knowing that experimental error is inevitable, the hypothesis is that the experimental value for vB will deviate slightly from the ideal vB calculated. Furthermore, the hypothesis is that the ideal values for both scenarios 1 and 2 should be the exact same, as they are both calculated using the dimensions and angle
Tires are thrown from tires because the centrifugal force expels snow, rocks, and other foreign objects.
Case Study: Force Field Analysis and Strategies for Change In this case study you are a charge nurse on a medical/surgical unit that just implemented a barcode medication administration system (BCMA) that the hospital spent millions of dollars to implement. You have noticed some staff resistance to this change and some nurses overriding the safety features of the system. Proper orientation and training has been provided, yet you have noticed that staff have developed “workarounds” to the system. Some reasons suggested for not following proper procedure include the system delaying medication administration to their patients due to it taking more time to use, not wanting to wake their patients, and the equipment not always working.
The file labeled “Newton’s 2nd Law” is to be opened. The cart’s mass along with the attachment of the sensor and the accelerometer are to be measured and recorded. Being carefully verified in order, the track is leveled and the Force Sensor is set to 10N and connected to...
In this experiment, the force acting upon the cart was gravitational force.
This implies that the height at which centripetal acceleration is equal to the gravitational acceleration is ∆h=r/2
Place the container onto the scales and take out all five of the bearings and hold them in your hand whilst pressing the tare button on the electronic balance to take it to zero. Place one of your bearings to see the mass, record it and take it out. Repeat this for each individual bearing making sure to press tare every time to receive an accurate
=== The rotational kinetic energy can be defined by the equation K=1/2 I ω2. Where I is the moment of inertia of the body about the axis of rotation. In this experiment, the flywheel rotates freely about a horizontal axis.
In his Principia, Newton gives definitions related to what he calls “the Mathematical Principles of Natural Philosophy”, the fifth of which is the definition of centripetal force. The given definition of centripetal force is “that by which bodies are drawn or impelled, or any way tend, towards a point as to a centre” (Newton, Def. V). Rather, centripetal force is the force that draws bodies toward a center, rather than away. One way to think about centripetal force is to consider gravity, as gravity is the force that pulls objects down towards the center of the Earth. If an object is thrown into the air, it will return down, for the centripetal force is acting upon it and drawing it towards the Earth’s center. Another way of considering centripetal force is to think of gravity on a much larger scale, for example the gravity that keeps the moon orbiting the Earth. Earth’s gravitational pull towards its center, the centripetal force, keeps the moon from continuing on the path of a right line, and instead keeps it orbiting in a circular fashion. When the moon would other wise move in a straight line, the centripetal force
Sir Isaac Newton is the man well known for his discoveries around the term, Motion. He came up with three basic ideas, called Newton’s three laws of motion.
... resultant speed and, by the definition of the tangent, to determine the angle of which the object is launched into the air.
