HP Module 2-2 Free Body Diagrams

A box is moving up and to the left. Which direction is the force of friction acting?

• down the ramp to the right

• up the ramp to the left

• perpendicular to the surface

What is the direction of the tension force from the attached rope?

• There is no tension in this picture.

• Perpendicular to the surface.

• Down the ramp to the left.

• Up the ramp to the right

Name the missing force...

• friction force

• tension force

• force of gravity

• applied force

Name the missing force...

• weight force
• normal force
• applied force
• frictional force

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

• normal

• abnormal

• static

• inertia

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

When completing a free-body diagram, how should you draw the force arrows on the "body"?

• with the arrow tail touching the body

• with the arrow point touching the body

• it does not need to touch the body

• it doesn't matter, tail or point can touch

Name the missing force...

• applied force
• weight force
• lift
• normal force
