The force that keeps objects on top of surfaces instead of letting them sink into the surface is known as:

• normal

• abnormal

• static

• inertia

Whenever an object is moving, there is always this force opposing the motion:

• inertia

• momentum

• friction

• applied force

Is it BALANCED? 

• Yes
• No

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

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
