Understanding Fluids: Newtonian and Non-Newtonian

What is a characteristic of Newtonian fluids?

• They have a constant viscosity regardless of force.

• Their viscosity changes with applied force.

• They are always solid at room temperature.

• They are always liquid at high temperatures.

Which of the following is an example of a non-Newtonian fluid?

• Water

• Oil

• Milk

• Cornstarch and water suspension

What happens to the viscosity of a dilatant fluid when a strong force is applied?

• It evaporates.

• It increases.

• It remains constant.

• It decreases.

Which fluid is known to decrease in viscosity when force is applied?

• Oil

• Water

• Ketchup

• Cornstarch and water suspension

What is required to make a non-Newtonian fluid at home?

• Cornstarch and water

• Milk and sugar

• Flour and water

• Oil and vinegar
