Science Motion Flashcards
The unit of speed you need to use in this class is
m/s
The distance vs. time graph of an object speeding up would look like
a curved line getting steeper
The velocity vs. time graph of an object speeding up going forward would look like
diagonal up to the right, and in the positive
The velocity vs. time graph of an object speeding up in reverse (the negative direction)
diagonal down to the right, and in the negative
If you are traveling a certain distance, and the speed doubles, what should happen to the time needed?
it will be half
The position vs. time graph of an object moving with a constant speed in the positive direction from BEHIND the detector would look like
diagonal up to the right, in the negative
The velocity vs. time graph of a non-moving object would look like
a horizontal line at zero
During the race, the tortoise has the greatest average speed.
True
If you were accelerating (changing speed), what would your DISTANCE vs. TIME graph look like?
It would be curved
A position graph of an object moving away from the detector at a constant speed would look like
A straight line going up and to the right
If an object moving in one direction caused the line on a DISTANCE vs. TIME graph to be down and to the right, movement at the same speed but in the opposite direction would cause
A line with the same steepness, but slanting up to the right
The position vs. time graph of an object moving with a constant speed in the positive direction (away from the detector) will be…
diagonal up to the right, and in the positive
In general, if an object is traveling at uniform speed, at it travels for twice as much time, its distance traveled should
double
During the race, the toroise has the greatest instantaneous speed.
false
If you were accelerating (increasing speed) at a uniform rate, what should your VELOCITY (speed) vs. TIME graph look like?
A straight, diagonal line (similarly, this is sort of redundant, since lines are straight by definition).
