Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects.
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.
Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.
Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.
Conduct an 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.
