What is the definition of "weight"?

• measure of the force of gravity on your body
• the time it takes to get on a ride 
• the amount of matter in an object
• the size of an object

This is the amount of "stuff" in an object

• weight
• gravity
• mass
• volume

The amount that gravity pulls on you is called

• mass
• volume
• density
• weight

What do you use to measure the mass of an object?

• Thermometer
• water displacement method
• a scale
• length times width times height

Weight is a measure of the force of gravity pulling down on an object.

• True
• False

6000 g = ______ kg

• 60
• 6
• 600

The mass of a book on a table is 1.2 kg.  The normal force on the book is

• 0.12 N
• 1.2 kg
• 1.2 N
• 11.8 N

If weight on Earth = 54 N, mass =

• 530 kg
• 5.50 kg
• 54 kg
• 5.05 kg

unit for normal force (in all physics equations)

• N
• kg
• pound
