gravity
friction
applied force
tension
magnetism
13
Multiple Choice

gravity
friction
applied force
tension
magnetism
14
Multiple Choice
______ is a contact force that is applied to an object by a person or another object.
gravity
friction
applied force
tension
magnetism
15
Multiple Choice
______ is the force that is transmitted through a string, rope, cable, or wire when it is pulled tight by forces acting from opposite ends.
gravity
friction
applied force
tension
magnetism
16
Multiple Choice
______ is a contact force that resists the sliding motion of two surfaces that are touching.
gravity
friction
applied force
tension
magnetism
17
Multiple Choice
Forces can cause objects to
stop moving only.
start moving only.
start moving, change direction, or stop moving.
change direction only.
18
change in motion.
unbalanced force can be in opposite directions or the same direction
When forces are unbalanced:
motion is constant
there is no motion
When forces are balanced:
Balanced and Unbalanced Forces
balanced forces are equal. unbalanced forces are not equal
100N
75N
75N
75N
19
Multiple Choice
Which of these is evidence that an unbalanced force is acting on an object?
The mass of the object is changing
The object remains at rest.
The motion of the object is changing
The object continues moving in a straight line at constant velocity.
20
When forces are unbalanced, the net force > 0
When forces are balanced the net forces = 0
Net force is the SUM of all forces acting on an object
balanced forces are equal. unbalanced forces are not equal
100N
75N
75N
75N
21
the Newtons that are going in the SAME DIRECTION
Add
the Newtons that are going in the OPPOSITE DIRECTION
Substract
How to calculate Net Force
Remember:
Determine the direction and magnitude of each individual force first
when subtracting, subtract the smaller number from the larger number
22
Multiple Select
What is the net force (direction and magnitude) on this object?
(Hint: select two options)
4N
Left
Right
0N
No direction since the forces are balanced
23
Multiple Choice
What is the net force (direction and magnitude) acting on the box?
30N, right
30N, left
5N, left
25N, left
24
Multiple Choice
What is the net force (direction and magnitude) acting on the box?
100N, left
90N, right
