Centripetal force is provided by the tension in the spring a stroboscope is used to stop the motion so that at one flash per revolution, the rotor appears to be stationary. 7/07 1 centripetal force lab saddleback college physics department, adapted from pasco scientific 1 purpose to use a pasco apparatus containing a rotating brass object to confirm newton's second law of.

Physics 3204 core lab #2: centripetal force and centripetal acceleration pre- lab questions: 1 define uniform circular motion 2 a boy ties a rock to a 20 m string and holding it at the very end whirls it around himself. From this, frequency of the motion can be determined and hence centripetal force on the mass to determine the actual force required to stretch the spring enough to hold the weight over the indicator, a string is connected to the mass and passed over to the pulley. Centripetal force lab purpose: 1 to study the nature of centripetal force 2 to measure the relationship between centripetal force, mass, and velocity.
In this animated physics video, your students will learn about centripetal force and newton's second law this video was made for the pbs learning media library, thanks to a generous grant from nasa. 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. Examples of forces which can provide the centripetal force include gravitation (for planetary orbits), friction (for cars rounding a curve), normal force (for roller coaster loops), or, in the case of this experiment, tension in a string. 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. In this lab we will observe how centripetal force varies with different radii by setting fc equal to a known force, we can test the accuracy of the experiment 1) find fc for two different radii by measuring the radii then recording the period based on a reasonable number of revolutions.
In this experiment, the centripetal force is the restoring force of a stretched rubber band with one end attached to the shaft of a dc permanent-magnet motor powered by your lvps and the other end attached to a # 6-32 nut. In this physics lab, we'll be examining the effect of centripetal force on an object moving in a circle by using a bucket filled with water, you'll be able to understand how the centripetal force. So far in the lab, we had two labs of static equilibrium cases, f=0 (lab #1 &2), two cases of f=ma (lab #3 & 4) when there is non-zero net outside force acting on a system, the system will have acceleration. For this lab, strength of the centripetal force is fixed by the distance stretched by the spring namely, it is constant because of that, the answer of question 1 is not straightforward as you simply look at f c =mv.
A force sensor measures the centripetal force exerted on a mass as it moves in a circle a photogate can be used to measure the angular speed different masses can be added to the platform and positioned at variable radii. Ap physics 1 investigations 78 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. Centripetal force lab report advertisement centripetal force lab gage ames em delarme and zack armagost physics - period 2 wednesday, march 4, 2009 purpose to be able to understand and verify the relationship centripetal force, mass, velocity, and the radius of orbit for a body that is undergoing centripetal acceleration. Physics practicai report set 1_1 centripetai force page 7 of 12 chan cheuk lok 6b (1) (6) the circular path of the rubber bung may not be horizontal to the ground. Physics lab report centripetal force essay centripetal force f is the net force causing the centripetal acceleration of an object performing uniform circular motion its magnitude is given by the equation: f = mrs.
A rock tied to a post moves in a circle at constant speed on a frictionless horizontal surface all the forces acting on the rock are shown: tension t, support force n by the table, and the force due to gravity w. Physics lab report impulse essay impulse and momentum lab part i: as the first lab of the physics 2 curriculum, our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. Guidelines for a physics lab reports a laboratory report has three main functions: (1) to provide a record of the experiments and raw data included in the report.
Many times, friction is the source of the centripetal force suppose in our initial example that a car is traveling through a curve along a flat, level road a freebody diagram of this situation would look very much like that of the block on the end of a string, except that friction would replace tension. Purpose: the purpose of this lab is to investigate the relationship between the speed of an object in uniform circular motion (ucm) and the centripetal force on the object. Force and acceleration in circular motion introduction acceleration is the time rate of change of velocity since velocity is a vector, it can change in two ways: its magnitude can change and its direction can change. Using this velocity, calculate the centripetal acceleration and centripetal force and record in the table as 'a c , calculated' and 'f c , calculated', then find the % difference between the measured.
