Upthrust

What is the volume of Object X?

• 10.0 cm³
• 15.0 cm³
• 20.0 cm³
• 25.0 cm³

Archimedes' Principle states that... 

• The buoyant force acting on an object equals the volume of the fluid displaced by the object. 
• The buoyant force acting on an object equals the weight (force of gravity) of the fluid displaced by the object.
• The buoyant force acting on an object will always be equal. 

The ship was able to float in the water because its weight was the same as the weight of the water it displaced.

• True
• False

Objects A-D are in water. Which is the most dense?

• A
• B
• C
• D

The density of this material is 2 g/cm³.
There are 24 cm³  Find the total mass.

• 12 grams
• 48 grams
• 12 g/cm³
• 48 g/cm³

This is 3 cm x 2 cm x 2 cm.  If it has a density of 5 g/cm³ Tell me what the mass is of the entire object.

• 5/12 g
• 5 g
• More information is needed!
• 60  g

What happens to the pressure in a liquid as the depth increases?

• It decreases

• It remains the same

• It increases

• It fluctuates

What is the formula for calculating pressure in a column of water?

• p = h * ρ * g

• p = m * a

• p = F/A

• p = v/t

What will an object placed in a fluid do if its weight is equal to the upthrust?

• Float

• Sink

• Dissolve

• Expand

What will an object placed in a fluid do if its weight is greater than the upthrust?

• Sink

• Float

• Remain unchanged

• Evaporate
