Friction

Front

What is friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

In which direction does friction act in relation to movement?

Back

Friction acts in the opposite direction of movement.

Front

How does the roughness of a surface affect friction?

Back

Rougher surfaces have greater friction compared to smoother surfaces.

Front

Which surface would create more friction: carpet or tile?

Back

Carpet would create more friction than tile.

Front

What is the best description of friction?

Back

Friction is best described as a rubbing force.

Front

What factors affect the amount of friction between two objects?

Back

The amount of friction depends on the roughness of the surfaces and how hard the objects are pressing together.

Front

True or False: The amount of friction increases with the weight of the objects in contact.

Back

True.

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

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

Back

The coefficient of friction is a numerical value that represents the frictional force between two surfaces; higher values indicate greater friction.
