Seemingly simple actions around us, such as car tires spinning or a satellite orbiting a planet, have much more complex processes at hand. In Unit 3, you will continue to build upon your understanding of the physical world using representations to form a more complete and complex model of motion as it relates to gravitational mass and inertial mass. Specific preconceptions will be addressed in this unit, such as the idea of a centrifugal force.

The exam weight of this unit is 4-6% and it tends to span over approximately 7-9 forty-five minute class periods.

Applicable Big Ideas ๐Ÿ’จ

Big Idea #1: Systems - Objects and systems have properties such as mass and charge. Systems may have an internal structure.

Big Idea #2: Fields - Fields existing in space can be used to explain interactions.

Big Idea #3: Force Interactions - The interactions of an object with other objects can be described by forces.

Big Idea #4: Change - Interactions between systems can result in changes in those systems.
