Forces and Free-Body Diagrams in Circular Motion - Directions
Using the Forces in Circular Motion Concept Builder is quite simple. You will be presented with a verbal description of an object moving in circles. You will have to think about the situation that is being described and identify the free-body diagram that is consistent with the situation. You can select the free-body diagram by tapping on the diagram section on the right side of the Concept Builder. Tapping allows you to toggle through the six options for answers. Once you'e toggled through all six, you can recycle through the options a second time. The field above the diagram indicates what option you are viewing. Once you have selected your option, stop tapping. Then tap on the Check Answer button. Your answer will be evaluated and your Progress Report will be updated. Your goal is to earn "Stars" and to complete one or more activities. Stars are earned when you show success on a particular question. Once you show success on all the questions for a particular difficulty level, you will earn the reward for level.
