Answer 1

Answer:

Car

Explanation:

Friction is a force between two surfaces that are sliding, or trying to slide, across each other. Friction always slows a moving object down. The amount of friction depends on the materials from which the two surfaces are made. The rougher the surface, the more friction is produced.

Answer 2

Answer:

make the table wet

Explanation:

the water makes the surfaces smoother, so there is less friction. Less friction makes it harder to stop.
