FLASHCARD QUESTION

Front

What is friction?

Back

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

2.

FLASHCARD QUESTION

Front

What factors affect the amount of friction between two surfaces?

Back

The roughness of the surfaces and the normal force acting between them.

3.

FLASHCARD QUESTION

Front

What is the coefficient of friction (μ)?

Back

The coefficient of friction is a dimensionless scalar value that represents the frictional force between two bodies in contact.

4.

FLASHCARD QUESTION

Front

How does surface roughness affect friction?

Back

Rough surfaces have greater friction due to increased interlocking between the surfaces.

5.

FLASHCARD QUESTION

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

6.

FLASHCARD QUESTION

Front

What factors influence terminal velocity?

Back

The weight, size, and shape of an object influence its terminal velocity.

7.

FLASHCARD QUESTION

Front

What is normal force?

Back

Normal force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.
