The force that opposes motion
2
What is friction?
3
Unit to measure force
4
What are newtons?
5
An object that appears to
stay in place used in
relation to a moving object
6
What is a reference point?
7
Change in position over
time
8
What is motion?
9
Combination of forces
acting on an object
10
What is net force?
11
Acceleration in a circle
12
What is centripetal
acceleration?
13
What is different when two
cars have the same speed
but travel in different
directions.
14
What is velocity?
15
What you have if you ride a
bike at the same speed and
don’t turn
16
What is constant speed and
constant velocity?
17
This DOES NOT happen if
you ride a bike at a
constant speed and velocity
18
What is acceleration?
19
Three vocabulary words to
describe slowing down
20
What are deceleration,
negative acceleration and
acceleration?
21
The distance traveled
divided by the time taken
to travel the distance
22
What is speed?
23
The average speed of a car
that goes 100 miles in 2
hours, takes a 1 hour break
and then travels another 60
miles in an hour
24
What is 40 mph?
25
Two forces act on an object.
One force is 10N south and
the other is 15 N north.
Describe the amount and
direction of the net force
26
What is 5N north?
27
How to find acceleration
28
What is change in velocity
over time?
29
Acceleration of an object
going from rest to 10 m/s in
5 seconds
30
What is 2/m/s/s?
31
Two factors that determine
the amount of friction
32
What are the force and the
roughness of the surfaces?
33
How you know if there is
static friction
34
What is the object doesn’t
move?
35
An object used to reduce
friction
36
What is a lubricant?
37
On solid surfaces, this type
of friction is usually the
lowest.
38
What is rolling friction?
39
Why lighter objects can go
faster
40
What is less mass has less
force, so there is less
friction to slow it down
41
Definition of a force
42
What is a push or a
pull?
43
How forces acting in the
same direction are
combined.
44
What is they are added
together?
45
Forces that do NOT cause
an object to move.
46
What are balanced forces?
47
Changes in velocity
(accelerations) are caused
by this type of force.
48
What are unbalanced
forces?
49
Net force required to move
an object
50
What is a net force greater
than zero?
