Science Friction Flashcard

Front

What is friction?

Back

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

Front

True or False: Friction always opposes motion.

Back

True

Front

Name the three types of friction.

Back

Static friction, kinetic friction, and rolling friction.

Front

Which type of friction occurs when an object is not moving?

Back

Static friction.

Front

What is the force that opposes the motion of an object due to friction called?

Back

Frictional force.

Front

What is static friction?

Back

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

Front

What is kinetic friction?

Back

Kinetic friction is the frictional force acting between moving surfaces.

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of a rolling object.

Front

How does surface texture affect friction?

Back

Rough surfaces increase friction, while smooth surfaces decrease friction.

Front

What is fluid friction?

Back

Fluid friction is the resistance encountered by an object moving through a fluid (liquid or gas).
