Circular Logic - Directions

Using the Circular Logic Concept Builder is quite simple. You will be presented with the circular path for an object's motion that has eight labeled positions. The object moves clockwise - from A to B to C to D ... etc. You will be asked to determine the direction of one or more of the motion vectors - velocity, acceleration, or net force - at one of the positions along the circular path. A default direction (up) is given. You can tap on the corresponding change button to toggle through the set of 8 different answer options. The direction of the vector changes upon each tap. Once you have the direction as desired, 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 levels of difficulty. Stars are earned when you show success on a particular question. Once you show success on all the questions at a particular difficulty level, you will earn the reward for that level.
