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 amount of friction depends on the roughness of the surfaces and the normal force pressing them together.

3.

FLASHCARD QUESTION

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on objects that are sliding over each other.

4.

FLASHCARD QUESTION

Front

What is the role of normal force in friction?

Back

Normal force is the perpendicular force exerted by a surface on an object resting on it, and it affects the amount of friction.

5.

FLASHCARD QUESTION

Front

How does surface roughness influence friction?

Back

Rougher surfaces tend to have greater friction due to increased interlocking of surface irregularities.

6.

FLASHCARD QUESTION

Front

What is an example of helpful friction?

Back

Helpful friction includes the grip of shoes on the ground, which prevents slipping.

7.

FLASHCARD QUESTION

Front

What happens to an object in motion if there is no friction?

Back

An object in motion would continue to move at a constant speed in a straight line, according to Newton's first law of motion.
