1.1.3

Identify qualitative observations in the following text:

A group of students were testing whether a battery-powered toy car would move differently on smooth and rough surfaces. On the tile floor, it made a loud rattling noise as it rolled. The car’s speed increased from 0.4 meters per second to 0.9 meters per second when it was placed on the smooth ramp. The students thought the car moved faster on the smooth surface because there was less friction slowing it down.
