Physics velocity acceleration and force -- Project

Click For Summary

Homework Help Overview

The discussion revolves around a physics project involving velocity, acceleration, and force, with experimental trials measuring the distance traveled by a toy truck and the time taken. Participants are attempting to analyze their data and understand the relationships between the variables involved.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants express uncertainty about the specific requirements of the project, particularly regarding which equations to use for calculating acceleration and force. There is mention of needing to create graphs and confusion about the different velocity equations. Some participants suggest that a clearer explanation of the experimental setup is necessary.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the project requirements and expressing confusion about the calculations and the experimental setup. Some guidance has been offered regarding the need for a diagram and the importance of explaining the methodology, but no consensus has been reached.

Contextual Notes

Participants mention needing to create three graphs (distance vs. time, velocity vs. time, acceleration vs. time) and the requirement to compare their findings to the F=ma equation. There is also a concern about potential errors in calculations and the clarity of the project instructions.

Homework Statement


We did two trials she didn't really go over it. first trial (1m, 1.50 seconds), (1.30m, 2.00 seconds) (1.5, 3.22); second trial (1m, 1.45), (1,30m, 2.03), (1m, 1.46) The mass of the weighted object is 50 and 200 g for the one in the car. We measured how far the toy truck traveled and the time till the end of the board. I'm thinking I should be trying to solve for the acceleration, but idk if that's what she's asking for

Homework Equations


V=d/t, A=V/t, and at=v, f=ma

Yeah and with that description I have no idea what you're asking either. Good luck.

We are supposed to do graphs on excel i guess and yeah i don't know which equation I'm supposed to start with. There are two velocity equations, the teacher mentioned using the graphs to determine the acceleration. So i have no clue. LOL. We are supposed to end with the Force equation.

We are supposed to have three graphs one with distance vs time, velocity vs. time, acceleration vs. time. But there are two Velocity equations... :( idk
 
It's still not clear what you did.

It sounds like there was a pulley and a hanging weight ('the weighted object') ? Draw a labelled diagram of the experimental set up.

We have to find the slope (Acceleration) and compare it to the F=ma equation. And the measurements that I'm getting are different. I'm guessing I messed up on the calculations.. :(

Maybe.
We'll never know unless you explain what you did and what you are trying to do.

this post still applies:
