This document contains a 15-question pre-test in science with multiple choice answers. It covers topics on motion, speed, waves, and sound. The questions test understanding of concepts such as what defines an object in motion, how to calculate average speed, properties of transverse waves, and characteristics of high and low frequency sounds. Sample calculations and diagrams are provided to aid in answering some of the questions.
