Preparing for a measurement For each of your trials, you will swing the stopper overhead so that the stopper exhibits uniform circular motion around the acrylic tube. You might get wet!
When we time the motion for a number of revolutions we can find the distance traveled and calculate the velocity. Practice until you can do this is one smooth motion every time.
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.
Swing it fast enough to keep the item from falling out. You can use a balloon to demonstrate centripetal force. It tries to keep moving in the same direction.
Amusement rides use centripetal force to achieve sudden twists or complete vertical loops without dislodging passengers. Also there were a couple of times where the weight wasn't completely over post; sometimes the spring was not stretched enough and sometimes it was stretched too much.
We adjusted the post to where the weight was directly above the post.
Note how fast the ball is swinging Stop the swinging and now add more weight to the paper clip end. We also did the calculations for the mass of 0. Duct tape will secure the ball the best Hold the paper clip string with one hand Hold the cardboard tube with the other hand and start to swing the ball end of the string over your head until you get the feel for the swinging Now stop the swinging and this time attach an object to the other end of the string onto the opened paper clip.
I also learned that the centripetal force to stretch the spring with a weight attached moving in a circular path is equal to the force required to pull the string.
The measured minimum value for force was found to be. Bend the paper clip, and tie the loose end of the string to the center of the paper clip. We then put a centripetal force apparatus on the table and leveled it by adjusting the legs appropriately.
Really, there is no force pushing you outward. The table represents all of our calculations. Thusly, if a force is kept constant perpendicular to the direction of motion then uniform motion along an arc with radius r is achieved.
Because the number of washers on the string is the same, the tension is also the same. Model of a Carousel Centripetal Force The speed of a moving body and its direction of movement remain constant according to Newton's first law law of inertia if no force acts on it.
Hence, the following equality holds: Now stop moving the balloon and watch what happens to the hex nut. On the merry-go-round, you are holding yourself onto the ride, exerting a force that keeps you from flying off to travel in a straight line. In this case there must be a force, the so-called centripetal force, which is directed to the axis of rotation.
More Science Experiments Have you ever put a coin in one of those wishing wells that is shaped like a giant funnel? As you swing the ball around your head, the other end lifts up.
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.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.
Centripetal force is the force on an object on a circular path that keeps the object moving on the path.
It is always directed towards the center and its magnitude is constant, based on the mass. Any force can act as a centripetal force be it gravity, tension, friction, or a combination there of. The experiment again. 6. For the Force vs. Time graph click on the Highlight Range icon near its top left to make a highlight box appear in the Force vs.
Time graph. This means that when the velocity is higher, the centripetal force increases and when the velocity is lower, the centripetal force is less. This is explained through the equation Fc=mv^2/r. We can use the method of ones to sample this experiment.
The formula for centripetal force is: (f) = mass of the object (m) * tangential velocity (v) squared / distance from the center or radius (r). Centripetal force is measured in Newtons, and one Newton equals pounds, according to Education Portal.
calculate the experimental centripetal force applied to the brass object. Note: the M here is the mass of the brass object.
The hanging mass has already been used to calculate your theoretical centripetal force. Record the experimental centripetal force for each radius. 3.Download
