What is the role of brakes on a bike?

Back

Brakes use friction to slow down or stop the bike.

Front

What is the effect of surface texture on motion?

Back

Different surface textures can increase or decrease friction, affecting how far an object rolls.

What is the north pole of a magnet?

Back

The north pole of a magnet is the end that points toward the Earth's North when freely suspended.
