Centripetal force lab saddleback college physics department, adapted from pasco scientific 1 purpose the centripetal force experiment requires that the rotating platform assembly be extremely level analysis and results for part i: 1. A push centripetal force also keeps you in your seat on a loop of a loop-de-loop roller-coaster ride and when you're making a turn on your bicycle cleanup throw the jell-o in the trash when you. The tendency of a moving object to continue in a straight line in the absence of an unbalanced force and to turn in a circle in the presence of a inward-directed force (ie, centripetal force) is a common experience as a passenger in an automobile. The experiment was successful because we were able to obtain reasonable results our hypothesis was proven correct because in our results the greater the mass the greater the centripetal force and acceleration were some errors that may have occurred during the experiment was mistiming from the. Comparing the findings with the centripetal force formula (f=mv2/r), they are not correct the findings showed 1/r3, while the formula would simplify to f=1/r when only factoring radius it took a while to figure out the best, accurate method to doing this experiment.
Centripetal force purpose: in this lab we will study the relationship between acceleration of an object moving with uniform circular motion and the force required to produce that acceleration. Lab 5 - uniform circular motion introduction if you have ever been on an amusement park ride that travels in a curved or circular path, then you have experienced a force, called a centripetal force, pushing you into the ride. This activity, you’ll experiment with centripetal force, and learn how it works in your own golf swing string, 80 centimeters long tape measure marker cork thread spool (or straw cut in half) tape metric scale (optional) stopwatch 3 small objects of different weights to be. A centripetal force (from latin centrum, center and petere, to seek) is a force that makes a body follow a curved path analysis of several cases below are three examples of increasing complexity, with derivations of the formulas governing velocity and acceleration.
Ap physics 1 investigation 3 where r is the radius of the object’s motion, v is the speed, and is the angle the string makes with the vertical, as shown in figure 1. Intro to newton's 2nd law, followed by centripetal force explanation and planning activity based around the rubber bung on a string practical adapted from another users ppt who also has an uploaded worksheet for the practical which i gave to pupils who couldn't plan their own investigation. The magnitude of centripetal acceleration is given by a centripetal = v 2 /r thus at the bottom of the swing, the net force (tension - weight) is responsible for the centripetal acceleration. Find the best estimate for the centripetal force that was generated at a given/fixed velocity 10) the instrument for this experiment has both a data table and data display. Aim the aim of the investigation is to see how the centripetal force on an object changes when we change 3 input variables: mass speed and the distance from the centre of the circle – the radius.
Table 2 shows the plotted data of frequency to log10 to the centripetal force to log10 which has an equation of y = 03133x + 03713 as seen the graph we can conclude that our experiment’s hypothesis is conclusive to the data collected. 40 experiment 7: centripetal force advance reading text: centripetal force, gravitational force objective to measure the centripetal acceleration of a body in circular motion and to determine the centripetal force. Centripetal force is any force pulling inwards on an object to maintain its motion in a circle - in your case the force of your arm pulling on the bucket as it swings centrifugal force has two possible meanings. In this experiment, the relationship between frequency and radius, mass and centripetal force is, 1) the radius is inversely proportional to the frequency of the circular motion when the centripetal force is constant. To use graphical analysis techniques to derive/verify the equation for centripetal force to investigate the behavior of friction in circular motion note: careful study of part ii of the lab guide is essential to your success in this lab.
Centripetal force by: alexander jones abstract in this experiment newton’s first and second laws of motion were used to study and verify the expression for the force, f, to be provided to mass, m, to execute circular motion. In this collection, the idea of a centripetal force is consistently used we begin with qualitative experiments that focus students’ attention on the direction of the force causing a circular motion later experiments are quantitative acceleration, a, needs a force, f,. Experiment 1: balancing centripetal force in this experiment, you will investigate how the magnitude of radius affects the time period of an object with circular motion materials 1 aluminum tube 1 m. Centripetal force (last edited december 29, 2011) dr larry bortner learning objectives in the analysis of motion, centripetal is the word we use to describe both the acceleration and the force required to change the straight line motion.
In this investigation you will use the force sensor to measure the centripetal force acting in the pendulum, as it swings the light gate enables you to measure the speed of the pendulum bob at the bottom of the swing. Centripetal force any motion in a curved path represents accelerated motion, and requires a force directed toward the center of curvature of the path this force is called the centripetal force which means center seeking force. - 11-experiment m5 centripetal force objectives: • to improve your understanding of circular motion • to verify the expression for the centripetal force, f = mv2/r • to determine the relationship between the period of rotation and the centripetal force. 8 whenthevelocityisconstant,askyourcolleaguetostarttimingatacertainpointyouagree uponandsimultaneouslycount10completedcyclesbythebigmetal(100 g)mass.
