#### SCI-MS.PS2.01 6th Grade (SCI) Physical Science Standards
[PS2] Motion and Stability: Forces and Interactions

##### SCI-MS.PS2.01 Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects.

Clarification Statement: Emphasis is on balanced (Newton’s First Law) and unbalanced forces in a system, qualitative comparisons of forces, mass and changes in motion (Newton’s Second Law), frame of reference, and specification of units.
Disciplinary Core Ideas
PS2.A: Forces and Motion The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion.
