Friction

Front

What is the definition of friction?

Back

Friction is the force that acts in the opposite direction of motion when two surfaces come in contact.

Front

How does friction affect the speed of an object?

Back

More friction decreases speed.

Front

What type of friction do swimming fish experience?

Back

Fluid Friction.

Front

What kind of friction slows down the movement of a swimmer?

Back

Fluid Friction.

Front

What is the relationship between surface roughness and friction?

Back

Rough surfaces have greater friction compared to smoother surfaces.

Front

What are the two main 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 that acts between moving surfaces.

Front

How does the coefficient of friction relate to the force of friction?

Back

The force of friction is equal to the coefficient of friction multiplied by the normal force.

Front

What factors affect the amount of friction between two surfaces?

Back

Surface roughness, material properties, and the normal force.
