{{:forces:girl-motion-790x50.jpg|Forces & Motion Banner}} ====== UNDERSTANDING FORCES (Force, Motion & Gravity) QUIZ: ====== Keywords: [[http://www.physicsclassroom.com/class/newtlaws/Lesson-1/Balanced-and-Unbalanced-Forces|'unbalanced forces']], [[http://en.wikipedia.org/wiki/Gravity|'gravity']], [[http://en.wikipedia.org/wiki/Simple_machine|'simple machines']], [[http://www.sciencebuddies.org/science-fair-projects/project_experiment_fair_test.shtml|'fair test']], [[http://en.wikipedia.org/wiki/Inertia|Inertia]] === THIS IS A QUIZ - IT IS NOT A TEST === 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. === Questions are designed to encourage students to: === - Explore and describe forces and motion - Explore and describe gravity’s effect on an object - Experiment and observe the effect that different-sized forces have on objects - Ask BIG questions === Concepts such as stationary and moving objects, and forces are explained: === * Objects are stationary because the forces acting on them are balanced. For example, a book on a table is being pulled down by gravity and the table is pushing up. These forces are of the same magnitude in different directions and so they cancel each other out. To make a stationary object move, a new unbalanced force must be applied. * Forces can be demonstrated through direct contact, such as physical pushes and pulls, or apparently at a distance, such as {{https://www.youtube.com/watch?v=pwh4wvXWRuA|gravity}} and [[https://www.youtube.com/watch?v=1TKSfAkWWN0|magnetism]]. **Forces transfer energy to objects and it is the energy (movement or kinetic energy) that enables objects to move.** ====== Getting Started: ====== === At the end of this section you will find a link to an on-line QUIZ. === 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. === Please read the next few lines before you try the QUIZ: === * For each question, there is one or more on-line videos that you should watch that will help you understand the question better and will help you select the correct answers. * Many of the questions include 'interactive' and/or [[http://en.wikipedia.org/wiki/Simulation|'simulator']] software. * After you have worked through the questions, videos and simulators, attempt the QUIZ again (you may attempt the QUIZ as many times as you like). * If you do get any answers wrong, then check out the videos and interactives and ask your friends and teachers for help. * Do the videos or ideas that they raise give you any ideas about experiments that you would like to try yourself? * If you find any interesting videos or links, make a note of them so that you can share them in class, * Make a note in the DISCUSSION sections for questions that you would like to discuss or that you would like answered in class. === Before you start, take some time out, to consider this video about forces: === {{ youtube>GmlMV7bA0TM?640x360 |Gravitational Forces}} === Video 1.
