  long-range forces.
- Demonstrate proficiency in accurately drawing and labeling
  free-body diagrams.

4.2 Vector Addition
- Determine the resultant of two vectors.

4.3 First Law of Motion
-  Define mass and inertia.
-  State and apply Newton’s first law of motion for objects in static
  equilibrium.

4.4 Mass and Weight
- Distinguish between mass and weight and calculate weight using
  the acceleration due to gravity.

4.5 Second Law of Motion
- Understand the significance of Newton’s second law of motion and
  use it to solve problems.
