graphs&slope Flashcards
on a distance/postion time graph, what can tell you the motion?
drawing a line of best fit
what does a straight line on a time graph represent?
uniform motion
what does a steep line on a distance/position time graph indicate?
a fast speed
for a distance/position time graph, what does a shallow line indicate?
a slow speed
what does a flat horizontal line on a distance/position time graph indicate?
zero speed, the object is stationary
what is the formula for calculating slope on a distance/position time graph?
slope = rise
run
=change in distance (>d)
change in time (>t)
=df-di
tf-ti
=speed
what is the formula to calculate slope on a speed time graph?
slope = rise
run
=change in speed (v)
change in time (>t)
=_________________
(—-> acceleration)
what does a horizontal line mean on a speed time graph?
zero slope = uniform motion
what does a positive slope indicate on a speed time graph?
the speed is speeding up
what does a negative slope
on a speed time graph indicate?
the speed is slowing down
what is the process for calculating area on a speed time graph?
area = length x width
= (v) x (>t)
= distance
what does the area under the line represent on a position/distance time graph?
the acceleration of the object
what does the area under the line indicate on a speed time graph?
the distance of the object
What would a position time graph look like for uniform motion? non-uniform motion?
uniform motion = consistent diagonal line
non-uniform motion = horizontal line straight across graph
what would a velocity time graph look like for uniform motion? non-uniform motion?
uniform motion: consistent horizontal line across the graph
non-uniform motion: curving line that is not consistent
