Fluids

Question 1

What is dynamic friction?

Answer 1

A force that is constantly trying to remove energy

Dynamic friction occurs when an object is in motion and experiences resistance due to contact with another surface.

Question 2

What is static friction?

Answer 2

Stops something from starting to move

Static friction acts on objects that are not moving and prevents them from starting to move.

Question 3

What is the definition of friction?

Answer 3

A force that resists movement

Friction is the resistance that one surface or object encounters when moving over another.

Question 4

What does viscosity refer to?

Answer 4

How easily a fluid flows

Viscosity is a measure of a fluid’s resistance to flow, with higher viscosity indicating a thicker fluid.

Question 5

More friction = less flow = _____________

Fill in the blank

Answer 5

Higher Viscosity

Question 7

What is flow?

Answer 7

Particles move around each other and take the shape of their container.

Question 8

What states of matter exhibit flow?

Answer 8

Liquids, gases, and plasma.

Question 9

How do forces affect flow?

Answer 9

Forces change the behavior of particles in flow.
