The purpose of the QUIZ is to encourage students to research answers for themselves and then have an opportunity to get guidance from their friends and from their teacher.
Forces transfer energy to objects and it is the energy (movement or kinetic energy) that enables objects to move.
When starting out, students are NOT expected to be able to answer many of the QUIZ questions correctly - if any at all.
As the course progresses and knowledge increases, students will have additional opportunities to test their new understanding about each of the questions.
Parents and teachers may point students to related information; do not tell them the answers.
