What is the definition of friction?

Back

Friction is a rubbing force that opposes motion between two surfaces in contact.

Front

What factors affect the amount of friction between two surfaces?

Back

The roughness of the surfaces and the force pressing them together affect the amount of friction.

Front

What is the relationship between surface texture and friction?

Back

Rough surfaces have more friction, while smooth surfaces have less friction.

Front

What is the role of gravity in experimental design?

Back

Gravity must be considered in experiments involving motion, as it affects the behavior of objects.
