Friction and Free Body Diagrams

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

The down-arrow in this diagram is most-likely:

• gravity

• normal

• a push or pull

• friction
