UNIT 2. VECTORS AND EQUILIBRIUM

At the end of this unit the student should be able to:

- Distinguish between vectors and scalars

- Add vectors using graphical and analytical methods

- Distinguish between contact forces and field forces by identifying

  the agent that causes the force

- Demonstrate proficiency in accurately drawing and labeling free

  body diagrams

- State and apply Newton’s first law of motion for objects in static

  equilibrium

- Define and calculate the torque of a given force about an axis of

  rotation

- State the two conditions of equilibrium: translational and rotational

  and apply them to solve for unknown forces and/or distances in a

  variety of situations
