What is the formula for pressure?

• P = F * A

• P = F / A

• P = F + A

• P = F - A

What is the unit of measurement for pressure?

• Newtons

• Pascals

• Kilograms

• Pounds

What principle states that a pressure applied to a fluid is transmitted throughout the whole fluid?

• Boyle's Law

• Pascal's Principle

• Archimedes's Principle

• Bernoulli's Principle

What is the relationship between the velocity of a fluid and its pressure according to Bernoulli's Principle?

• As velocity decreases, pressure increases

• As velocity increases, pressure decreases

• As velocity increases, pressure increases

• As velocity decreases, pressure decreases

What did Archimedes realize about buoyancy?

• The buoyant force on an object is equal to the weight of the fluid displaced by the object

• The buoyant force on an object is equal to the volume of the fluid displaced by the object

• The buoyant force on an object is equal to the pressure of the fluid displaced by the object

• The buoyant force on an object is equal to the density of the fluid displaced by the object

What is the ability of a fluid to exert an upward force on an object placed in it called?

• Density

• Pressure

• Volume

• Buoyancy

What is the effect of altitude on air pressure?

• As altitude increases, air pressure increases

• As altitude decreases, air pressure decreases

• As altitude increases, air pressure decreases

• As altitude decreases, air pressure increases
