Understanding Pressure and Density Quiz

What is the formula for calculating pressure?

• Pressure = Force × Area

• Pressure = Force ÷ Area

• Pressure = Mass × Volume

• Pressure = Mass ÷ Volume

• 98 N

• 10 N

• 9.8 N

• 100 N

Which of the following factors does NOT affect drag force in fluids?

• Speed of the object

• Surface area of the object

• Colour of the object

• Density of the fluid

What is the relationship between mass, volume, and density?

• Density = Mass × Volume

• Density = Mass ÷ Volume

• Density = Volume ÷ Mass

• Density = Mass + Volume

If a block of wood has a volume of 50 cubic feet and a mass of 100 pounds, what is its density?

What happens to the pressure if the area over which a force is applied is increased?

• Pressure increases

• Pressure decreases

• Pressure remains the same

• Pressure doubles

Which of the following best describes drag force?

• A force that acts in the direction of motion

• A force that opposes the motion of an object through a fluid

• A force that acts perpendicular to the motion

• A force that increases the speed of an object

• 2.4 kg

• 2 kg

• 3 kg

Which of the following statements is true about weight and mass?

• Weight is the same as mass

• Weight is a force and mass is a measure of the amount of matter

• Mass changes with location, weight does not

• Mass is measured in newtons, weight in kilograms
