Force of Friction Flashcard

Front

What is the relationship between the normal force and the force of friction?

Back

The force of friction is directly proportional to the normal force.

Front

How do you find normal force from mass?

Back

Normal force is mass times gravity.

Front

What is the role of the coefficient of friction in the frictional force equation?

Back

The coefficient of friction represents the roughness of the surfaces in contact.

Front

What is the normal force of a 50-Newton object as it rests on a flat surface?

Back

50 N

Front

What is the effect of the surface area in contact on the force of friction?

Back

The force of friction remains the same regardless of the surface area in contact.

Front

Define friction.

Back

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

Front

What are the two types of friction?

Back

Static friction and kinetic (or dynamic) friction.

Front

What is static friction?

Back

Static friction is the frictional force that prevents two surfaces from sliding past each other.

Front

What is kinetic friction?

Back

Kinetic friction is the frictional force acting between moving surfaces.

Front

What factors affect the force of friction?

Back

The nature of the surfaces in contact and the normal force.
