Physics Quiz 2

What is the principle that states an object completely or partially submerged in a fluid experiences an upward force equal to the weight of the fluid displaced by the object?

• Archimedes' principle
• Bernoulli's principle
• Pascal's principle
• Newton's first law of motion

What is the principle that states if a fluid increases in velocity, there will be a corresponding decrease in the fluid's pressure?

• Archimedes' principle
• Bernoulli's principle
• Pascal's principle
• Newton's second law of motion

What is the ability of a fluid to cause an object to float or suspend in it called?

• Buoyancy
• Density
• Inertia
• Frictional force

What is the ratio between a substance's mass and its volume called?

• Density
• Buoyancy
• Inertia
• Pressure

What is the force of resistance that results as moving objects come into contact with their surroundings called?

• Frictional force
• Gravitational force
• Tension force
• Normal force

What is the force exerted on an object placed in a fluid that acts in the opposite direction to the weight of the object?

• frictional force
• drag force
• resistance force
• buoyant force

How do balanced and unbalanced forces affect the motion of an object?

• Balanced forces cause the object to accelerate, while unbalanced forces do not
• Unbalanced forces cause the object to accelerate, while balanced forces do not
• Both balanced and unbalanced forces cause the object to accelerate
