Types of friction

Front

What is sliding friction?

Back

Sliding friction is the resistance that occurs when two surfaces slide against each other. It is the type of friction experienced when a pencil leaves marks on paper.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving when a force is applied. It helps you walk without slipping.

Front

What is rolling friction?

Back

Rolling friction is the resistance that occurs when an object rolls over a surface, such as a wheel on a road.

Front

What is fluid friction?

Back

Fluid friction is the resistance encountered by an object moving through a fluid (liquid or gas). An example is a fish swimming in water.

Front

How does friction affect motion?

Back

Friction opposes the motion of objects, slowing them down or preventing them from moving.

Front

What direction does friction act in relation to movement?

Back

Friction acts in the opposite direction of movement.

Front

What type of friction is involved when you apply brakes on a bike?

Back

Sliding friction is involved when you apply brakes on a bike, as it slows the bike down.

Front

True or False: Static friction can prevent slipping when walking.

Back

True.

Front

What type of friction is experienced when a book slides across a table?

Back

Sliding friction.

Front

What type of friction occurs when a ball rolls on the ground?

Back

Rolling friction.
