AI Thread Summary
The discussion revolves around the discrepancy between calculated and experimental acceleration in a physics lab involving a car and weights. Factors contributing to this difference include friction, air resistance, and measurement errors, which can affect experimental results. Newton's laws, particularly the second law of motion, are relevant in understanding these discrepancies. Participants are seeking clarification on how these variables impact the results. Understanding these concepts is crucial for accurately interpreting experimental physics data.

So we did a lab this week in my physics class.

We had a car on a horizontal table, that was attached to a string with weights (The weights were over the edge of the table.) We then calculated the experimental acceleration and the calculated acceleration. These numbers were different.

My teacher asked us "What was causing the difference between the calculated accel. and experimental acceleration..."
He also mentioned something to do with Newton's laws.

Do you know the answer/Can help me out?

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
