Uniform Accelaration?

<p>I took a Physics test recently and I am not completely sure of the answer to a question. The question was: “Which 2 graphs show uniform acceleration?”</p>

<p>Graph 1: Position-Time graph with a line with a positive slope
Graph 2: Velocity-Time graph with a horizontal line (this was basically the derivative of Graph 1)
Graph 3: Velocity-Time graph with a curving line (like half a quadratic equation)
Graph 4: Velocity-Time graph with a line with positive slope</p>

<p>I put 4 and 3 even though 3 seems like non-uniform acceleration to me.</p>

2

<p>only 4</p>

<p>3 is a increasing acceleration</p>

3

<p>Yes, I know that it was only 4. Nevertheless, it said choose 2 graphs.</p>

4

<p>I’d think that Graph 2 might work as the other graph because a horizontal line would show that it’s not accelerating. So if you want to get technical, it’s accelerating at a constant rate of 0 m/s^2.</p>

<p>^^…but you could also use that logic for graph 1.</p>

<p>Hmm…good point.</p>

<p>Those thoughts all went through my head in that order, which is why I chose 4 and 3.</p>

<p>Oh, 1 and 2 was not even a multiple choice answer and 4 is obviously one of the right answers.</p>
