Homework Help Overview
The discussion revolves around understanding the significance of the area under an acceleration-time graph in physics. Participants are exploring the relationship between acceleration, velocity, and the implications of the area calculation.
Discussion Character
- Conceptual clarification, Assumption checking
Approaches and Questions Raised
- Participants attempt to define what the area under the graph represents, with some suggesting it relates to instantaneous velocity and others clarifying it as the change in velocity. Questions arise regarding which initial velocity is relevant and the time interval considered.
Discussion Status
The discussion is active, with participants providing insights and questioning assumptions about the initial conditions and the interpretation of the area under the graph. There is no explicit consensus yet, but the dialogue is productive in clarifying concepts.
Contextual Notes
Participants are considering the implications of the area between two time values, specifically distinguishing between the present time and an initial time reference.
What does the area under an acceleration-time graph give?

hi tahayassen! 
strictly, instantaneous velocity minus initial velocity

Oh, because it gives you the change in velocity. Opps!

Actually, which initial velocity are we talking about? The initial velocity of that instant?

"the area under" must mean "between two values of t" …
one value is the present time, the other value is what we usually call the initial time
one value is the present time, the other value is what we usually call the initial time
