UCP 2: Evidence, models, and explanation
UCP 3: Change, consistency, and measurements
SAI 1: Abilities to do scientific inquiry
SAI 2: Understanding about scientific inquiry

PS 4a: Objects change their motion only when a net force is applied. Laws of motion are
used to calculate precisely the effects of forces on the motion of objects. The
magnitude of the change in motion can be calculated using the relationship F = ma,
which is independent of the nature of the force. Whenever one object exerts force on
another, a force equal in magnitude and opposite in direction is exerted on the first
object.
