Matter

A state of matter that has a definite volume and shape.

• solid
• liquid
• gas
• matter

What was the principle Archimedes discovered?

• Principle of Volume
• Principle of Density
• Principle of Buoyancy
• Principle of Gravity

What is buoyant force?

• An upward force exerted by fluids on an object.
• An downward force exerted by fluids on an object.

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. 

which of the following statements is true?

• oil floats on water because oil is less dense than water
• oil does not float on water because water is more dense
• water floats on oil because water is less dense

has a weight of 15 N and a buoyant force of 18 N

• sinking object

• floating object

• buoyed up object

• nothing happen

______________ has a weight of 10 N and a buoyant force of 10 N.

• A density

• A sinking object

• A floating object

• A buoyed-up object

Pascal's Law states that

• any pressure applied to the surface of a fluid is transmitted uniformly throughout the fluid in all directions

• any pressure applied to the volume of a fluid is transmitted uniformly throughout the fluid in all directions

• any pressure applied to the surface of a fluid is transmitted not uniformly throughout the fluid in all directions

• any pressure applied to the surface of a fluid is transmitted uniformly throughout the fluid in any directions

What pressure does a 4000N horse exert on the ground if each foot is 10cm²?
