# Cetripetal force experiment

Similarly, a display of the moons of Jupiter would illustrate how centripetal force holds objects of different sizes and densities according to their distance and rate of travel. Our data proves our hypothesis right.

Either way the only thing that would change would be the frame of reference and so I would always be right. Centrifugal force depends on the solid walls of the bucket to appear to exist, while centrifugal force behaves according to the fixed rules of nature. The experimental value is the equation found through the data in the experiment.

This method, which should seem familiar from The Pendulum experiment, minimizes the uncertainty in the period estimate, which is the largest source of error in this lab.

Each group can do the activity on their own. Which path would the stopper follow? Answer the following questions: A centripetal force is NOT a new, real force that exists by itself; rather, it must be provided by some other force to keep an object moving along a circular path.

Your Pasco line has a high profile in our Cetripetal force experiment and will continue to do so far into the future.

First we calculated the linear speed for each trial and found an average. The ball moves outward as you swing it and that is called centrifugal force.

It will not dump onto your head unless you stop swinging the bucket halfway around! To help keep this constant during a trial, fasten the cord clamp onto the string one centimeter from the bottom end of the tube. Because if they were two sides of the same coin then you could use them kind of interchangebly.

Lots of amusement park rides work because of the laws of physics. Hold the acrylic tube vertically so that the washers hang below, and carefully swing the stopper overhead. People are standing along a round wall, facing towards the center. You can use a balloon to demonstrate centripetal force.

You should keep the radius constant, which means swinging the apparatus as uniformly as possible. So the accepted value is 0. This makes sense because the faster you spin something, the force on that object that is pulling it away is greater. Repeat this experiment except this time around, add a g slotted weight to the hanging weight.

Once everything was set up, we then measured the radius of the apparatus from the center of the rotating pole to the string where the weight hung from. Basically, are both of these sentences correct?

If you swing too hard, the weight will lift up really quickly. We also solved for the force of the hanging mass These were the calculations for the mass of 0. Why is it that more objects are harder to keep inside? Cetripetal force experiment I mean, of course the indicate two different things, but the only thing that would change would be the point of view, the frame of reference. It defines how gravity works, and explains the orbits of the planets and moons. The water and the bucket both move outwards during the swing.

Because of course the centripetal force would go towards the center of the merry-go-round, but it is just thanks to the centripetal force if there's the centrifugal one.

We also did the calculations for the mass of 0. I think I understood that you use the term centripetal or centrifugal according to the frame of reference, but I am not sure whether the centrifugal force is completely equal to the centripetal one, except for the fact that its direction is the opposite of the centripetal force.

In order to do that you must attach a string to the weight opposite of the spring and hang a mass hanger over the pulley of the apparatus. Thread the free end of the string through the acrylic tube.

Centripetal force is the product of the laws of motion and gravity. Steve Davala is a high school chemistry and physics teacher who likes to write.

To find it, we have to do experimental value minus accepted value over the accepted value. This is is a much larger percentage than expected.

It is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving. In this case, after plugging in the values, we get the percent error of Your group is going to experiment with the force they feel when pressed against the side of a car that is going around a curve really fast.

Holding the string taut, place the cord clamp onto the bottom portion of the string below the tube, approximately 1 cm away from the bottom of the tube.Learn about centripetal acceleration and centripetal force.

Centripetal Force Purpose The purpose of this experiment is to empirically determine the relationship between the angular velocity of a body in circular motion and.

PHYS Experiment 7-Centripetal Force rotating. Estimate the uncertainty dr of the radius. 6. Using the information in steps 2 and 5, calculate the speed v of the bob. This is given by v = distance/time = 2prn/t, where r is the radius of the circle and n the number of revolutions.

Notes: Lab Setup (see this page for photo details). The flag should be installed on the apparatus before lab, and removed before storage. A 5/64" hex head wrench is required (in the box).

Centripetal force is defined as the force acting on a body that is moving in a circular path that is directed toward the center around which the body moves. The term comes from the Latin words centrum for center and petere, meaning "to seek". Centripetal force may be considered the center-seeking force.
