Friction

Front

What is friction?

Back

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

Front

What factors affect the amount of friction between two surfaces?

Back

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

Front

How does surface roughness influence friction?

Back

Rougher surfaces have more friction due to increased contact area and interlocking of surface irregularities.

Front

What is the role of friction in everyday life?

Back

Friction allows us to walk without slipping, enables vehicles to stop, and helps objects stay in place.

Front

What happens to friction when a lubricant is applied?

Back

Applying a lubricant reduces friction by creating a slippery layer between the surfaces.

Front

In what direction does friction act in relation to motion?

Back

Friction acts in the opposite direction of the movement.

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 water affect friction on a water slide?

Back

Water reduces friction on a water slide, allowing for a smoother and faster descent.

Front

What is the effect of friction on the motion of objects?

Back

Friction causes objects to slow down or stop.
