forces are measured in
Newtons
m/s
kg
weight
this represents
a push or pull to the left
a push or pull to the right
two forces that are equal in size and opposite in direction
balanced force
unbalanced force
force of gravity
normal force
a balanced force results in a net force of
1 N
4 N
10 N
0 N
a balanced force
will cause a change in acceleration
will not cause a change in acceleration
an unbalanced force results in a net force
equal to zero
not equal to zero
What is the net force of 10 N of force pull to the right, and 3 N of force push to the right:
7 N
10 N
13 N
30 N
What is the net force on an object if 50 N of force push up, and 50 N of force pull down
50 N
100 N
0 N
55 N
A force of 50 N pushes to the right, and a force of 20 N pushes to the left, the object will
accelerate
not accelerate
a _______ force is always a push directed at right angles (perpendicular) to the surface
normal force
applied force
force of gravity
tension force
The force that opposes motion between two objects sliding past each other. (opposite the applied force)
normal force
applied force
force of gravity
force of friction
The force that pulls objects together (a ball falling to the ground)
normal force
applied force
force of gravity
force of friction
this force diagram shows
an object moving to the right
an object at rest
an object falling
an object slowing down
this force diagram shows
an object moving to the right
an object at rest
an object falling
an object slowing down
this force diagram shows (notice the applied force is bigger than the friction force)
an object moving to the right
an object at rest
an object falling
an object slowing down
this force diagrams shows
an object moving to the right
an object at rest
an object hanging from a cord
an object slowing down
Which of the following is a force that can occur over a distance: (without touching)
normal force
applied force
magnetic force
friction
An area of space that surrounds an object allowing a force to be exerted:

Which is the correct unit for weight: HINT: weight is a FORCE
kg
g
W
N
A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them. (Think about the penny and the notecard we did in class!)
Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction.
Newton's 1st Law (Law of Inertia)
Newton's 2nd Law (Law of Acceleration)
Newton's 3rd Law (Action/Reaction)
Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more mass and requires more force to accelerate.

What statement is true?
Mass never changes. Weight does.
Weight never changes. Mass does.
Both mass and weight change because they are affected by gravity.
Neither mass nor weight change. They are always the same.
