Homework Help Overview

The discussion revolves around a lab experiment related to Newton's Second Law, specifically focusing on collecting data for acceleration when varying weights are added to a cart system. The original poster seeks assistance in obtaining this data to calculate the force of gravity.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to gather data from others who have conducted the same lab experiment, expressing a need for specific acceleration values corresponding to different weights. Some participants question the poster's approach to obtaining data and suggest alternative methods for acquiring necessary information.

Discussion Status

The discussion includes various suggestions for the original poster, such as contacting the teacher for an extension or asking classmates for help. There is no explicit consensus on how to proceed, but multiple avenues for obtaining data are being explored.

Contextual Notes

Participants note that the original poster missed the class due to a family trip, which has impacted their ability to collect data firsthand. The importance of demonstrating work in calculations and graphing is also mentioned, indicating that data collection is not the sole focus of the assignment.

Newtons 2nd Law experiment

Homework Statement



I need some data for labexperiment 11 Newtons second law in which you add weights to a hanging weight which pulls a cart through a photogate. Anyway i was wondering if anyone else has done this lab because i need data for the acceleration of the system when the weight has .05 .07 .09 .11 and .13 (kilograms) so i can calculate the force of gravity

Homework Equations



F=MA

The Attempt at a Solution



I know i need to calculate the Force of gravity with the mass of the system however in order ot do so i must know the acceleration which i regretfully do not have.

So what you're asking is has anyone done this lab, so you can copy their data? why didn't you do this is class?

I can't really help you as I never did an actual lab, I instead did it algebraically, acceleration due to gravity (neglecting friction, and on Earth at approx seas level, I forgot the radius) is 9.8m/s.

I guess if you want to say it like that yea i need some data, however data is not important in this labit is the work we show in calculating the force of friction as well as graphs and I was not in the classs to get the data i was on a family trip and came back as we got out of school for a week and a half winter break.
 


ask your teacher over the email for an extension or ask a friend

or if you have no friends (kidding :) ) then email your teacher and ask for numbers.
 


I agree, explain to your teacher that you were away with your family and ask how you can (properly) obtain the data you need to complete the assignment.
