Understanding Friction and Fluid Dynamics

Which of the following is true about fluid friction?

• It only occurs between solid surfaces.

• It is also known as dry friction.

• It can occur in both air and water.

• It does not depend on the nature of the fluid.

What term describes a fluid's resistance to flow?

• Elasticity

• Buoyancy

• Viscosity

• Density

How does the viscosity of honey compare to that of water?

• Honey is less viscous than water.

• Honey is more viscous than water.

• Viscosity does not affect fluid friction.

• Honey and water have the same viscosity.

What happens to fluid friction as the speed of an object increases?

• It decreases.

• It remains constant.

• It increases.

• It becomes negligible.

Why are airplanes designed with a streamlined shape?

• To increase air resistance.

• To minimize fluid friction.

• To reduce weight.

• To improve fuel efficiency.
