Unit A section 3 &4

Jack has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7 mL
• 7 g/cm³
• 28 g/cm³
• 1/7 g/cm³

I have two objects with the same volume but different masses.  Which object will be more dense?

• The object with less weight.
• The object with more weight.
• The object with more mass.
• The object with less mass.

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

Frank has an eraser. It has a mass of 4g, and a volume of 2cm³. What is its density?

• 8 g/cm³
• 2 g/cm³
• 1/2 g/cm³
• 24 g/cm³

What force causes the wood to float 

• weight
• density
• buoyant
• gravity

whose principle says buoyant force = the weight of the fluid an object displaces 

• Archimedes
• Pascal
• Bernoulli
• Einstein 

If you place an object in a fluid and it sinks which is true 

• its weight is less than the buoyant force
• the fluid is more dense than the object
• its weight  is greater than the buoyant force
• dead men tell no tales
