9
A Change in position.
10
What is motion?
11
The rate of change in distance.
12
What is speed?
13
This is described by knowing the speed and
direction.
14
What is velocity?
15
The change in position between the starting
point and the ending point.
16
What is displacement?
17
A rocket accelerates at 12 m/s for 8s. If it
starts at rest, what is its final speed?
2
18
96 m/s
19
The rate of change in velocity.
20
What is acceleration?
21
Acceleration can occur in these three ways.
22
What is speeding up, slowing down, and changing
direction.
23
Acceleration can be calculated using this
equation.
24
Accelerationfinal speed -initial speed
time
25
When you are speeding up you have this type
of acceleration.
26
What is positive acceleration?
27
This is a train's acceleration when its
speed increases from 7m/s to 18 m/s over a
period of 120 s.
28
0.092 m/s
2
29
The measure of how hard it is to stop the object.
30
What is momentum?
31
Momentum is changed when you exert this on an
object.
32
What is force?
33
When a toy truck collides with a toy car,
the momentum of these is the same before and
after the collision.
34
What is the truck plus the car?
35
The momentum of a compact car with a mass of 725
kg moving at 30 m/s.
36
What is 21,750 kgxm/s?
37
The velocity of an object with a momentum of 600
kgxm/s.
38
What is 12 m/s?
39
This is the amount of matter in an object.
40
What is mass?
41
kgxm/s
42
What are the units used to measure momentum?
43
m/s

44
What are the units used to measure acceleration?
45
kg
46
What are the units used to measure mass?
47
This is the velocity of a 10-kg object with a
momentum of 50 kgxm/s.
48
5 m/s
49
Acceleration involves a description of these.
50
What is speed and direction.
51
On a speed-time graph, a horizontal line shows
the change in speed is this.
52
What is zero?
53
This describes the motion of a car with an
acceleration of -2m/s .
2
54
What is the car is slowing down 2m/s every
second.
55
This is the speed you read from your speedometer.
56
What is instantaneous speed?
57
Daily Double!!
58
This is the type of acceleration you have when
your speed changes from 10km/h to 6km/h.
59
What is negative acceleration?
60
This is the rate of change of velocity.
61
What is acceleration?
62
This is found by dividing the total
distance traveled by the time taken.
63
What is average speed?
64
This is the tendency of an object to resist a
change in its motion.
65
What is inertia?
66
This is the speed of an object at one istant in
time.
67
What is instantaneous speed?
68
This is the acceleration of a car that goes from
80km/h to 20km/h in 0.5h.
69
What is -120km/h ?
