<p>The graph of Potential Energy vs Time for an object falling from a building would look like a line with negative slope or like like a curve with potential energy decreasing over time?</p>
<p>It would be a line with a negative slope.</p>
<p>thank you kitts95</p>
<p>No, it would not be linear. U=mgh, so potential energy is linear in h, but not in t. h varies as -t^2, so you would have a concave down parabola.</p>
<p>^RandomHSer is correct, potential energy is a linear function of height, and for falling objects, height is a function of t^2. The graph would be a parabola, pointing downward.</p>
<p>AHHH! I’m so sorry - I must have misread the question. Please disregard my first post and thank you for correcting me guys!</p>
