4 The Physical Setting
For Grades: 9-12
Learning Goal 1
The change in motion (direction or speed) of an object is proportional to the applied force and inversely proportional to the mass.
Learning Goal 2
All motion is relative to whatever frame of reference is chosen, for there is no motionless frame from which to judge all motion.
Learning Goal 4
Whenever one thing exerts a force on another, an equal amount of force is exerted back on it.
Learning Goal 8
Any object maintains a constant speed and direction of motion unless an unbalanced outside force acts on it.
