Free-Body Diagrams Refresher

What is a free-body diagram used for?

• To measure the temperature of an object

• To calculate the speed of an object

• To determine the color of an object

• To show the relative magnitude and direction of all forces acting upon an object

In a free-body diagram, what does the size of the arrow represent?

• The color of the force

• The temperature of the object

• The magnitude of the force

• The speed of the object

What is the first step in constructing a free-body diagram?

• Identify the forces acting on the object

• Measure the object's velocity

• Draw a box to represent the object

• Calculate the net force

What should you do after identifying the forces in a free-body diagram?

• Measure the object's temperature

• Draw arrows for each force

• Determine the object's speed

• Calculate the object's mass

What does the direction of the arrow in a free-body diagram indicate?

• The color of the object

• The speed of the object

• The temperature of the object

• The direction the force is acting

How is the object typically represented in a free-body diagram?

• As a circle

• As a triangle

• As a box

• As a star

What should each force arrow in a free-body diagram be labeled with?

• The object's color

• The object's temperature

• The type of force

• The object's speed

What is the purpose of the Free-Body Diagram Interactive mentioned in the text?

• To practice identifying forces and constructing free-body diagrams

• To determine the color of objects

• To measure the speed of objects

• To calculate the temperature of objects

What is the only rule for drawing free-body diagrams?

• Depict all the forces that exist for that object in the given situation

• Draw the object as a circle

• Use only red arrows

• Include the object's speed

What should you do if you have difficulty drawing free-body diagrams?

• Measure the object's temperature

• Calculate the object's speed

• Determine the object's color

• Review the list of forces and their descriptions
