Force and Motion - Directions

Using the Force and Motion Concept Builder is quite simple. You will be presented with a force diagram of a physical situation. The forces acting upon an object are represented by arrows. The direction of the arrow represents the direction of the force. And the size of the arrow represents the relative strength of the force. You will have to select the dot diagrams that correspond to the manner in which such an object would move. You can select all that apply. Selecting a dot diagram involves tapping on it once. Tapping a second time will deselect the dot diagram. Once selected, a red box surrounds the selected dot diagram. As long as at least one dot diagram is selected, a Check Answer button will be visible.Once you are satisfied with your answer, tap on the Check Answer button. Your answer will be evaluated and your Progress Report will be updated.
