MS-PS2-1 - Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects.

Clarification Statement - Examples of practical problems could include the impact of collisions between two cars, between a car and stationary objects, and between a meteor and a space vehicle.

Assessment Boundary - Assessment is limited to vertical or horizontal interactions in one dimension.
