Physical Science - Final Exam Practice Test

What is the definition of pressure in terms of force and area?

• Pressure is the force applied per unit area.

• Pressure is the area divided by force.

• Pressure is the sum of force and area.

• Pressure is the difference between force and area.

What is the formula used to calculate pressure?

• Pressure = Force / Area

• Pressure = Mass x Acceleration

• Pressure = Volume / Temperature

• Pressure = Energy x Time

Which scientist discovered that pressure in a confined fluid is transmitted equally in all directions?

• Isaac Newton

• Blaise Pascal

• Galileo Galilei

• Archimedes

How would you calculate the pressure if given a specific force and area?

• Pressure = Force × Area

• Pressure = Force ÷ Area

• Pressure = Area ÷ Force

• Pressure = Force + Area

Pascal’s Principle states that pressure applied to a confined fluid:

• is transmitted equally in all directions throughout the fluid.

• decreases as it moves through the fluid.

• only affects the surface of the fluid.

• increases with depth only.

How does a hydraulic lift amplify force through changes in piston area?

• By increasing the pressure in the smaller piston

• By decreasing the pressure in the larger piston

• By using a larger output piston to create a greater force from the same input pressure

• By reducing friction between pistons

The SI unit for pressure is:

• Pascal

• Newton

• Joule

• Watt

How can pressure be calculated when a force is applied over a surface area?

• By dividing force by area

• By multiplying force and area

• By adding force and area

• By subtracting area from force

What happens to output force in a hydraulic system when the output piston area increases?

• The output force increases.

• The output force decreases.

• The output force remains the same.

• The output force becomes zero.
