Understanding Zero Slope in Distance & Velocity Graphs

Click For Summary
A zero slope in a distance vs. time graph indicates that the object is not moving, meaning there is no change in distance over time. In contrast, a zero slope in a velocity vs. time graph signifies constant velocity, which can also mean the object is at rest if the velocity is zero. The discussion highlights the importance of understanding how slope relates to motion in these graphs. It emphasizes that a flat line on a distance vs. time graph represents no motion, while a flat line on a velocity vs. time graph indicates constant velocity. Overall, these concepts are crucial for analyzing motion in physics.

Well I assume when you learned early algebra, you learned that slope = change of y / change of x. Given that, what is the slope of a distance vs time graph equivalent to? (and what about velocity vs time?)
 


there is no motion. it means that the the object is standing still.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
