After you gather he data needed, you will sketch a TO versus extension graph. In the experiment a stopwatch is used to calculate the period of 20 complete oscillations however the reflex of a person pressing the stop button can differ so this creates a random error.
Repeat step 12 measure the length of the string from the top of the tube to the stopper. If the paper clips rises or falls appreciably as the stopper whirls then the radius of the circle is changing. With the paper clip against the bottom of the tube and the string pulled taut, measure the length of the string from the top of the tube to the stopper.
Measure the mass f the stopper and washer, m, and record it in the data and observations section. With the paper clip against the bottom of the tube and the string pulled taut, measure the length of the string from the top of the tube to the stopper.
Rubber stopper with a hole PVC tube or wooden spool 1. Then add g masses one by one to the mass hanger and record the extension of the spring and the time taken for that size of mass to complete twenty oscillations.
Contact force and Variable Radius 9. Repeat step 12 measure the length of the string from the top of the tube to the stopper. Why did you not have to do that on 5. Formulate an equation for the relationship between the spring force and the centripetal acceleration of the stopper.
I predict that the velocity of the stopper will increase as the radius is shortened. Repeat step 6 and record the data in table 1, data run 2.
Whirl the stopper while maintaining a constant force on the scale. The real value of g is measured as 9. Get Full Essay Get access to this section to get all help you need with your essay and educational issues. Stop the stopwatch after 30 rev.
You will be given an unknown mass and also record the time taken of that mass to oscillate twenty times. We accomplished our goal which was to relate the variables involved in uniform circular motion. As the radius increases so does the speed of the stopper.
These differences can be accounted as a random error also I could not press the timer at the exact time but it would not affect the accuracy of the experiment.Physics Lab Report – What Keeps a Stopper Moving in a Circle Essay Sample Hypothesis: I predict that the velocity of the stopper will increase as the radius is shortened.
Rubber stopper with a hole. How to Write Physics Lab Reports There are three questions to keep in mind when writing lab reports. 1. Could your friend (or your boss) read the report and understand exactly what you did? Lab reports are an essential part of all laboratory courses and usually a significant part of your grade.
If your instructor gives you an outline for how to write a lab report, use that. Some instructors require the lab report be included in a lab notebook, while others will request a separate.
A sample lab report for this activity is provided as an example for you to follow when writing future lab reports. Sample Lab Report: Experimental Investigation of C/D Abstract. Physics L Lab report 10 Archimede’s Principle I.
Abstract water, it will sink. In order to keep it from sinking, we support it was a string. The tension in the string T plus the buoyant force B acting on Documents Similar To Physics Lab Report Lab 9 Report-Buoyancy.
Uploaded by. hellboy Buoyant Force Laboratorium Activity.5/5(3). Physics Lab Report Statement of the Problem: The problem that was arisen in Problem #5: Motion up an Incline was in reference to a change in acceleration in both an uphill and downhill motion.
The question on hand was whether or not the acceleration was the same going uphill as it was downhill or different from each other in both directions.Download
