what does the gradient represent on a d-t graph?
velocity
which axis does d-t graphs have the time in s on
x-axis
what does the y-axis of a d-t graph represent
distance
what indicates travelling at a constant speed on a d-t graph?
straight line. contrantr gradient
what does a horizontal line on a d-t graph mean
travellin at a constant speed of zero (i.e. being stationary)
what does the are under a d-t graph mean?
nothing.
what does a curved line on a d-t graph represent [2 points]
acceleration/ deceleration
what are the axis of a s-t graph [2 points]
x-axis is time in s
y-axis is speed in m/s
what does the gradient of a s-t graph give?
acceleration
what does a stright line (constant gradient) on an s-t graph indicate
travelling with constant acceleration
what indicates constant speed on an s-t graph
horizontal line
what does ahorizontal line running across the y-axis mean
stationary
what represents high acceleration on an s-t graph
steep line
what represents low acceleration on an s-t graph
shallow line
how is acceleration represented on an s-t graph?
by a positive gradient
how is deceleration represented on an s-t graph?
negative gradient
what does the area under a s-t graph represent?
distance travelled
how to find the distance travelled in an s-t graph?
the area under
what is acceleration represented by an an s-t graph?
straight line
how is constant velocity represented as on an s-t graph?
horizontal line
give the equation linking acceleration, velocity change, and time taken
acceleration = change in velocity/ time
give the definitions of suvat
s - displacement
u - initial velocity
v - final velocity
a - acceleration
t - time
give the equation linking speed, distance, and time
s = d/t
