Acceleration of Velocity Graph: Finding the Relationship | Worsley School

AI Thread Summary
The discussion centers on interpreting a velocity graph to determine acceleration. It is established that the acceleration is zero for the entire duration of the graph, as the velocity remains constant except for instantaneous changes at specific points. If there were non-zero acceleration, the graph would exhibit a slope, indicating changes in velocity over time. The conclusion confirms that the acceleration graph would indeed be a straight line along the t-axis, representing zero acceleration. This understanding clarifies the relationship between velocity and acceleration in the given context.

Homework Statement

Is the acceleration zero for this entire velocity graph?


Homework Equations



v = delta x/ delta t
a= delta v/ delta t

The Attempt at a Solution



If i were to convert this velocity graph to an acceleration graph, i think it would be a straight line on the t-axis.

yes, the velocity is constant all the time, it just changes instantaneously at t=3 and at t=6. If there were non-zero acceleration the velocity would change over time and you would see a slope (upwards or downwards) in a velocity versus time graph.

thank you very much for the reply,

but just to make sure: so the acceleration graph of this velocity graph would be just a straight line on the t-axis ( 0 acceleration) ?
 
yes that's correct
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
