the distance of an object moving in a straight line
1 of 27
what does a straight line represent on a distance-time graph
stationary
2 of 27
what does a steep slope represent on a distance-time graph
the object is moving at a fast speed
3 of 27
what does a shallow slope represent on a distance-time graph
the object is moving at a slow speed
4 of 27
what does this distance time graph represent
constant speed
5 of 27
what does this distance time graph represent
stationary
6 of 27
what does this distance time graph represent
constant speed, back to orgin
7 of 27
what time of quantity is speed
scalar
8 of 27
what is the equation of average speed
average speed= distance moved/ time taken
9 of 27
what is acceleration?
acceleration = the rate of change pf velocity
10 of 27
what is the acceleration equation
acceleration = change in velocity/ time taken
11 of 27
an object which speeds up is called
acceleration
12 of 27
an object which slows down is called
decelerating
13 of 27
if an object is speeding up, acceleration is
positive
14 of 27
if an object is slowing down, its acceleration is
negative
15 of 27
what does a velocity time graph show
how the velocity of a moving object varies with time
16 of 27
increasing velocity on a velocity Time graph looks like
an increasing straight line
17 of 27
decreasing velocity on a velocity Time graph looks like
a decreasing straight line
18 of 27
the slope of the line on a velocity time graphs shows
magnitude of acceleration
19 of 27
what does the area under a velocity time graph represent
displacement/ distance travelled
20 of 27
if the shape is a triangle the formula is
area= 1/2 x base x height
21 of 27
if the shape is a square the formula is
area= base x height
22 of 27
what is the formula for an object with constant acceleration
v2 = u2 + 2as
23 of 27
what does SUVAT represent
S= distanced moved
U= initial speed in m/s
V= final speed in m/s
A= acceleration in ㎨
T= time taken

CORE PRACTICAL: what are the variable of the practical
Inderpendent=distance
Dependent=time
control= same object for each measurement
25 of 27
instructions for practical
1)Measure out a height of 1.0 m using the tape measure or metre ruler
2)Drop the object (paper cone or tennis ball) from this height, which is the distance travelled by the object
3)Use the stop clock to measure how long the object takes to travel this di
26 of 27
instructions for practical
4)Record the distance travelled and time taken
5)Repeat steps 2-3 three times, calculating an average time taken for the object to fall a certain distance
6) Repeat steps 1-4 for heights of 1.2 m, 1.4 m, 1.6 m, and 1.8 m
