FLASHCARD QUESTION

Front

What is friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

2.

FLASHCARD QUESTION

Front

What are the two main types of friction?

Back

The two main types of friction are static friction (when an object is at rest) and kinetic friction (when an object is in motion).

3.

FLASHCARD QUESTION

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from starting to move.

4.

FLASHCARD QUESTION

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of an object that is already moving.

5.

FLASHCARD QUESTION

Front

What is the normal force?

Back

The normal force is the force exerted by a surface that supports the weight of an object resting on it.

6.

FLASHCARD QUESTION

Front

How does surface roughness affect friction?

Back

Rougher surfaces generally produce more friction than smoother surfaces due to increased interlocking of surface irregularities.

7.

FLASHCARD QUESTION

Front

What is the coefficient of friction?

Back

The coefficient of friction is a numerical value that represents the frictional force between two surfaces in contact.
