Motion Unit Test Review

Sandra pushed a wooden block and it slid across the floor. The wooden block gradually slowed down and stopped after moving 10 meters.

Why did the block stop moving?

• The floor exerted a force that is opposite to the direction of the block’s motion.

• The block ran out of force.

• The floor absorbs force from the block.

• All objects stop moving because their natural state is to be still.
