Bend Description
In this bend, students will explore Newton’s laws of motion. Students will plan investigations to provide evidence that the
change in an objects motion depends on the forces acting on the object and the mass of the object. Students will apply
Newton’s third law (for every action there is an equal and opposite reaction) to design a solution to a problem involving the
motion of two colliding objects.
Student expected prerequisite knowledge
Common student misconceptions
 PS2.A (3-5) The effect of unbalanced forces on an
object results in a change of motion. Patterns of
motion can be used to predict future motion. Some
forces act through contact, some forces act even when
the objects are not in contact. The gravitational force
of Earth acting on an object near Earth’s surface pulls
that object toward the planet’s center.

Energy: Forces Affecting Motion (Bend 1 of 4)
In this bend, students will explore Newton’s laws of motion. Students will plan investigations to provide
evidence that the change in an objects motion depends on the forces acting on the object and the mass of
the object. Students will apply Newton’s third law (for every action there is an equal and opposite reaction)
to design a solution to a problem involving the motion of two colliding objects.
PS2.A: Forces and Motion
 For any of interacting objects, the force exerted by the first object on the second object is equal in
strength to the force that the second object exerts on the first, but in the opposite direction.
(Newton’s third law).
 The motion of an object is determined by 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.
 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.
 PS2-1 Apply Newton’s Third law to design a solution to a problem involving the motions of the two
colliding objects.*
 PS2-2 Plan an investigation 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.
 PS2-5 Conduct and investigation and evaluate the experimental design to provide evidence that fields
exist between objects exerting forces on each other even though the objects are not in contact.
