  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.
