Jacinda pushes her toy bus on a smooth tile. She then pushes it across a rough tile. How and why will the motion of the bus change?

• The bus would move faster on a smooth surface than on a rough surface because rough surfaces have more friction.

• The bus would move faster on a smooth surface than on a rough surface because rough surfaces have less friction.

• The bus would move faster on a rough surface than on a smooth surface because rough surfaces have more friction.

• The bus would move faster on a rough surface than on a smooth surface because rough surfaces have less friction.
