6th Grade (SCI) Physical Science Standards [PS2] Motion and Stability: Forces and Interactions
SCI-MS.PS2.02 Plan an investigation using Newton's First and Second Laws to provide
evidence that the change in an object's motion depends on the sum of the
forces on the object and the mass of the object.
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. A larger force
causes a larger change in motion. All positions of
objects and the directions of forces and motions
must be described in an arbitrarily chosen reference
frame and arbitrarily chosen units of size. In order to
share information with other people, these choices
must also be shared.
