Provide evidence to explain the effect of multiple forces, including friction, on an object. Include balanced forces that do not change the motion of the object and unbalanced forces that do change the motion of the object. Clarification Statements: Descriptions of force magnitude should be qualitative and relative; Force due to gravity is appropriate but only as a force that pulls objects down; State Assessment Boundaries: Quantitative force magnitude is not expected in state assessment; State assessment will be limited to one variable at a time: number, size, or direction of forces.
[3.PS.2.3] -
Conduct an investigation to determine the nature of the forces between two magnets based on their orientations and distance relative to each other. Clarification Statement: Focus should be on forces produced by magnetic objects that are easily manipulated.
[3.PS.2.4] -
Define a simple design problem that can be solved by using interactions between magnets.*
Clarification Statement: Examples of problems could include constructing a latch to keep a door shut and creating a device to keep two moving objects from touching each other.
