Friction

What is friction?

• A force that causes objects to move faster

• A force that pushes objects in the same direction

• A force that slows down or stops the movement of objects

• A force that pulls objects towards each other

Which force acts in the opposite direction of the wheels of a bike?

• Gravity

• Magnetism

• Friction

• Electricity

What happens when two surfaces rub against each other?

• They become smoother

• They become rougher

• They create friction

• They create magnetism

Which surface would give you less friction for ice skating?

• A smooth ice rink

• A rough concrete area

• A grassy field

• A sandy beach

How does the weight of an object affect friction?

• Heavier objects have less friction

• Heavier objects have more friction

• Weight does not affect friction

• Friction is only affected by the surface

When would you want less friction?

• When riding a bike

• When going down a slide

• When playing tennis

• When pushing a lawnmower
