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. 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.



Force and Motion 
 
Learning Goal:  To use an understanding of the effect of balanced and unbalanced forces upon the motion of an object in order to predict how an object will move under a certain set of force conditions.



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
?
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.




Match That Free-Body Diagram
?
Learning Goal: To identify the free-body diagram (FBD) that is consistent with a given physical situation.




Normal Force Card Sort
?
Learning Goal: To analyze a physical situation in order to determine the relative strength of the normal force experienced by an object. 




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.




Mass and Weight
?
Learning Goal: To distinguish between the concepts of mass and weight and to calculate the mass and the weight from given information.




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.




Net Force (and Acceleration) Ranking Tasks
?
Learning Goal: To use an understanding of Net Force and Newton’s Second Law to rank objects according to their net force and their acceleration.
 




Air Resistance and Skydiving
?
Learning Goal: To combine an understanding of the factors affecting air resistance with an application of Newton’s second law and kinematic concepts in order to analyze a skydiver’s motion.
 



Fnet = m•a
?
Learning Goal: To use Newton's second law equation to determine the individual force values required to cause a specified acceleration.




Solve It! with Newton's Second Law
?
Learning Goal: To use the Fnet = m•a equation to analyze situations involving unbalanced forces and accelerations.
