Concept 1: Motions and Forces
Analyze relationships between forces and motion.

PO 1. Determine the rate of change of a quantity (e.g., rate of erosion, rate of reaction, rate of growth, velocity).

PO 2. Analyze the relationships among position, velocity, acceleration, and time:
     • graphically
     • mathematically

PO 3. Explain how Newton’s 1st Law applies to objects at rest or moving at constant velocity.

PO 4. Using Newton’s 2nd Law of Motion, analyze the relationships among the net force acting on a body, the mass
of the body, and the resulting acceleration:
     • graphically
     • mathematically


PO 5. Use Newton’s 3rd Law to explain forces as interactions between bodies (e.g., a table pushing up on a vase
that is pushing down on it; an athlete pushing on a basketball as the ball pushes back on her).

PO 6. Analyze the two-dimensional motion of objects by using vectors and their components.

PO 7. Give an example that shows the independence of the horizontal and vertical components of projectile motion.

PO 8. Analyze the general relationships among force, acceleration, and motion for an object undergoing uniform
circular motion.


PO 9. Represent the force conditions required to maintain static equilibrium.

PO 10. Describe the nature and magnitude of frictional forces.

PO 11. Using the Law of Universal Gravitation, predict how the gravitational force will change when the distance
between two masses changes or the mass of one of them changes.

PO 12. Using Coulomb’s Law, predict how the electrical force will change when the distance between two point
charges changes or the charge of one of them changes.

PO 13. Analyze the impulse required to produce a change in momentum.

PO 14. Quantify interactions between objects to show that the total momentum is conserved in both collision and
recoil situations. 


Concept 2: Conservation of Energy and Increase in Disorder
Understand ways that energy is conserved, stored, and transferred.

PO 1. Describe the following ways in which energy is stored in a system:
     • mechanical
     • electrical
     • chemical
     • nuclear

PO 2. Describe various ways in which energy is transferred from one system to another (e.g., mechanical contact,
thermal conduction, electromagnetic radiation.)

PO 3. Recognize that energy is conserved in a closed system.

PO 4. Calculate quantitative relationships associated with the conservation of energy.

PO 5. Analyze the relationship between energy transfer and disorder in the universe (2nd Law of Thermodynamics).

PO 6. Distinguish between heat and temperature.

PO 7. Explain how molecular motion is related to temperature and phase changes.
