Whenever an object is moving, this force opposes the motion:
inertia
momentum
friction
applied force
If an object is moving to the right, this force is pushing or pulling to the left:
friction
applied
normal
tension
The force that keeps objects on top of surfaces instead of letting them sink into the surface is known as:
normal
abnormal
static
inertia
The force exerted by ropes and chains is called
tension
normal
elastic
mechanical
In a force diagram, or free-body diagram, the size/length of the arrow tells you this about the force:
relative strength
relative distance
relative direction
In a force diagram, or free-body diagram, the pointy-end of the arrow tells you this about the force:
relative strength
relative distance
relative direction
When determining the NET force on an object you should (TWO correct answers)
subtract forces in opposite directions
add forces in the same direction
divide by velocity
multiply by acceleration

If this object were moving right, the left-arrow in this diagram is most-likely:
gravity
normal
a push or pull
friction
