Ok Listen up...

A Graph shows distance on the vertical axis and time on the horizontal axis. If The Speed is steadily increasing, what will the line representing speed look like on the graph??

ok so odviously the answer is A Curved Line.

So with reguard to the question above , could any part of the speed line ever become perfectly vertical? Why or why not?

a) Yes, but only if the object stops moving.
b)yes, because eventually the speed would be so fast there would be no slope.
c)No, because it would require such a high speed that it would probably not be practical.
d)No,because that would mean you were covering a distance in zero elapsed time,which is impossible.

A graph of distance vs. time will be a parabola for an object undergoing constant acceleration.

A graph of speed vs. time will be a straight line (but not a horizontal line).

If the speed line becomes vertical, it means the object is undergoing infinite acceleration (acceleration being the time derivative, i.e., slope, of velocity). Infinite acceleration is not possible.

The answer is d).

The line would probably be a straight line from the lower left corner (where the axes meet) moving up and to the right.

If the rate of excelleration CHANGES, such as giving a car more gas as you gain speed, then the line would curve upwards.

Popping a wheelie on a motorcycle would would show a quick upward curving line (the wheelie) followed by a flat line straight across as the cyclist maintains a steady speed.
So the curve or direction of the line depends on the acceleration.

For me the closest to truth is D. For the graph to be completely vertical, there should be at least two different speeds happening in one exact time. Can something goes 1 mph and (not TO but AND) 2 mph in an exact same time? Correct me if I'm wrong but I don't think so. What's that Bernoulli work anyway?
