### Newton's Laws of Motion

A Concept-Builder is an interactive questioning module that presents learners with carefully crafted questions that target various aspects of a concept. Each Concept Builder focuses the learner's attention upon a discrete learning outcome. Questions target that outcome from a variety of angles using multiple difficulty levels or varying activities. Learners ponder the given information and answer questions in the hopes of earning Stars and Medals. These Stars (for answering questions) and Medals (for completing levels or activities) are displayed on the screen, allowing a teacher to track student progress. The following Concept Builders target concepts associated with Newton's Laws of Motion.

Balanced vs. Unbalanced Forces

Learning Goal:  To analyze a variety of representations of an object’s motion and to draw conclusions about the state of motion and the relative strength of the forces acting on the object.

Change of State
Learning Goal:  To identify the manner in which the individual forces must change in order for an object to change its state of motion.

Recognizing Forces (coming soon)
Learning Goal: To utilize an understanding of the various types of forces in order to analyze a given situation and to identify the presence or absence of a variety of force types.

Which One Doesn't Belong? Force and Motion
Learning Goal: To interpret various representations of an object’s motion in order to relate the relative strength of the forces that act upon the object to the subsequent motion of the object.

Newton's Second Law - Equations as Guides to Thinking
Learning Goal: To use Newton’s second law to predict the effect of varying net force and varying mass upon the acceleration of an object.

Tug of War (coming soon)
Learning Goal: BBB.
