Front

How can you create heat with your hands?

Back

You can create heat by rubbing your hands together.

Front

What happens when two surfaces rub against each other?

Back

They create friction, which can generate heat.

Front

What is an example of increasing friction?

Back

Wearing rubber rain boots increases friction between your feet and the ground.

Front

What is the effect of friction on motion?

Back

Friction slows down or stops the motion of objects.

Front

What materials can create more friction?

Back

Rough materials like rubber or sandpaper create more friction than smooth materials.

Front

Why does a nail feel hot after being pulled from wood?

Back

The wood rubs against the nail, creating friction and heat.

Front

What is one way to create heat without a lighter?

Back

Rubbing two sticks together can create heat.

Front

What is the relationship between weight and friction?

Back

Heavier objects usually create more friction because they press harder against the surface.

Front

How does surface texture affect friction?

Back

Rough surfaces create more friction than smooth surfaces.
