3-26-2012 We're All in Motion - CCCS for Science

5.2 Physical Science: All students will understand that physical science principles, including fundamental ideas about matter, energy, and motion, are powerful conceptual tools for making sense of phenomena in physical, living, and Earth systems science.


E. Forces and Motion :  It takes energy to change the motion of objects. The energy change is understood in terms of forces.

6	An object’s position can be described by locating the object relative to other objects or a background. The description of an object’s motion from one observer’s view may be different from that reported from a different observer’s view.	5.2.6.E.1	Model and explain how the description of an object’s motion from one observer’s view may be different from a different observer’s view.

6	Magnetic, electrical, and gravitational forces can act at a distance.	5.2.6.E.2	Describe the force between two magnets as the distance between them is changed.
6	Friction is a force that acts to slow or stop the motion of objects.	5.2.6.E.3	Demonstrate and explain the frictional force acting on an object with the use of a physical model.
6	Sinking and floating can be predicted using forces that depend on the relative densities of objects and materials.	5.2.6.E.4	Predict if an object will sink or float using evidence and reasoning.
8	An object is in motion when its position is changing. The speed of an object is defined by how far it travels divided by the amount of time it took to travel that far.	5.2.8.E.1	Calculate the speed of an object when given distance and time.
8	Forces have magnitude and direction. Forces can be added. The net force on an object is the sum of all the forces acting on the object. An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion at constant velocity will continue at the same velocity unless acted on by an unbalanced force.	5.2.8.E.2	Compare the motion of an object acted on by balanced forces with the motion of an object acted on by unbalanced forces in a given specific scenario.
