Circular and Satellite 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 Circular and Satellite Motion.


Circular Logic
 
Learning Goal: To identify the direction of the velocity, acceleration, and net force vectors for an object moving in a circle at constant speed.




Case Studies - Circular Motion
 
Learning Goal: To compare the velocity, acceleration, and net force of two different objects moving in circles with different radii, periods, speeds, and mass.




Forces and Free-Body Diagrams in Circular Motion
 
Learning Goal: To identify the free-body diagram (FBD) that is consistent with a given physical situation involving an object moving in a circle.




Universal Gravitation
 
Learning Goal: To use Newton’s law of universal gravitation to predict the effect of varying mass and varying separation distance upon the gravitational force between two objects.



Gravitational Field Strength
 
Learning Goal: To use the relationship between mass, distance, and gravitational field strength (g) to determine the strength of the gravitational field some distance from a planet.
