Questions these experiments will enable you to answer: What is the Hooke's Law constant, or spring constant, of my spring? How do the constants determined by different methods compare?
Physics 2211, Lab 8: Simple Harmonic Motion
Features: The mass hangs from a vertical spring attached to a force sensor. Automated measurements are made with devices that are interfaced to a computer and provide real time graphs of the force, position, and acceleration. The Hooke's Law constant is calculated from the proportionality between force and static position, from the period of the position as a function of time, and from the slope of the acceleration as a function of position. Preliminaries: Make sure the force sensor is plugged in to channel A of the interface unit and the motion sensor is plugged in to channels 1 yellow plug and 2 black plug of the interface unit.
The motion sensor should be on the far setting. Open the data template. You'll find graphical displays for position, acceleration, and force, as a function of time in Graph 1. Acceleration as a function of position will be found displayed in Graph 2. The mean values of the position and force will be displayed on their graphs. The motion sensor need not be calbrated. With the force sensor mounted vertically and no force applied, press the tare button on the body of the sensor.
Type 0 in the field for Calibration Point 1, and click Next. This tells the Capstone software what sensor output corresponds to zero force. Hang this mass from the force sensor. Type 2. This tells the Capstone software what sensor output corresponds to a force of 2. The force sensor is now calibrated. Click Calibrate again to and close the calibration window. While the calibration of the force sensor is quite stable over time, the tare is not.
You should remove the masses and hanger from the spring and tare the force sensor just before every measurement. If you wish, you may perform Experiment 1 and Experiment 2 for each mass, before performing them for the next mass.
Hang it from the spring, and bring any motion to a stop.More and more apps are delivering on-demand homework help to students, who can easily re-purpose the learning tools to obtain not just assistance, but also answers.400 gpm to psi
The new, seemingly magic app allows users to take pictures of typed equations, and then outputs a step-by-step solution. As of Wednesday, the app is the number one free app on the App Store. But if you want to learn, you can use PhotoMath for that. Sorting it by due date, week, month, or by course, the app is more organized than a Trapper Keeper.
Google Apps for Education. Packaging together favorites like Gmail, Hangouts, Google Docs, Google Sheets, and Google Drive with Classroom, a digital hub for organizing assignments and sending feedback, the goal of this collection is to make learning a more collaborative process. Though Google Apps for Education is cloud-hosted, the programs can be used offline, ideal for when your student needs to escape the internet and work distraction-free.
And since it works on any device, it also helps students avoid buying overly expensive hardware.Gravely zero turn front wheel bearings
That means more money for extracurricular activities. HwPic is a tutoring service that allows students to take send pictures of their homework to tutors, who will then respond within minutes to your questions with a step-by-step solution. Issa added that HwPic prohibits cheating in its terms and conditions. Wolfram Alpha. The service also outputs step-by-step solutions to topics as advanced as vector calculus and differential equations, making it a popular tool for college students.
Homework Helper. Chinese Internet search company Baidu launched an app called Homework Helper this year with which students can crowdsource help or answers to homework. Users post a picture or type their homework questions onto online forums, and those who answer the questions can win e-coins that can be used to buy electronics like iPhones and laptops.
The app has logged 5 million downloads, much to the dismay of many some parents who argue that the students spend less time thinking about challenging problems. Price: Free, but some homework services require payment Availability: iOS. Slader is a crowdsourcing app for high school and college students to post and answer questions in math and science. While students can post original homework for help, many questions in popular textbooks have already been answered on the app, according to Fast Company.
An Illinois high school said earlier this year that it suspected students were using the service to cheat on their math homework. Contact us at editors time. By Jack Linshi.

RealTime Physics : active learning labs transforming the introductory laboratory European Journal of Physics, Priscilla Laws. David Sokoloff. Ronald Thornton. RealTime Physics : active learning labs transforming the introductory laboratory. Please scroll down to see the full text article. This paper describes RealTime Physics, a sequenced introductory laboratory curriculum that is based on the results of physics education research, and uses computer-based tools to facilitate student learning.
Some figures in this article are in colour only in the electronic version Each year in the USA, over college and university students pass through introductory physics laboratories designed to help them acquire investigative skills and verify equations already presented in textbooks and lecture sessions. Each year over students do similar laboratory exercises in high school classes. The intent of introductory courses is to establish a basis for further study in physics, engineering and other experimental sciences.
Instructors also hope to interest students in further study in physics. Although there has been relatively little research on the educational value of weekly physics laboratory sessions , we do know that many students find traditional labs tedious and boring.
Revitalization of both the lecture and laboratory components of introductory courses is essential to the long-term health of physics as a discipline. In a traditional introductory physics laboratory, a student typically spends 2 or 3 h a week in the laboratory collecting data, performing calculations and graphing results that verify only one relationship.Adidas neo label
The time, effort and expense of maintaining laboratory programs, coupled with faculty and student concern about their educational value, has led some universities including prestigious research institutions such as Harvard and MIT to reduce or even abandon introductory laboratories.
In addition, by doing research on learning in laboratory settings, we can establish a basis for continuous improvement of student learning in laboratory programs. In this paper, we document that the RealTime Physics laboratory curriculum that we have developed can lead to dramatic improvements in student understanding of vital physics concepts. Microcomputer-based laboratory tools Beginning innew microcomputer-based laboratory MBL tools4 have become increasingly popular for the real-time collection, display and analysis of data in the introductory laboratory.
MBL tools consist of electronic sensors, a microcomputer interface, and software for data collection and analysis. Sensors are now available for measuring motion position, velocity and accelerationforce, sound, magnetic field, current, voltage, temperature, pressure, rotary motion, humidity, light intensity and many other physical quantities.
