Performance Objectives:
- Locate points, express angles, express rotation sense, and express distances in a Frame of Reference—the Cartesian
Coordinate System.
- Define scalar quantity.
- Define vector quantity.
- Distinguish between displacement and distance and speed and velocity.
- Relate average speed to distance traveled and time elapsed to solve problems involving such parameters.
- Define acceleration and suggest means for measuring it.
- Distinguish between average acceleration and instantaneous acceleration.
- Write three general kinematics equations that involve the parameters distance, initial velocity, final velocity, acceleration,
and time.
- Apply the kinematics equations to problem situation where the motion occurs under constant acceleration.
- Write the value of the acceleration due to gravity in both SI and English units.
- Describe the motion of a body in free fall when neglecting air resistance.
- Recognize that the equations of kinematics directly apply to bodies in free fall.
- Use the quadratic equation to determine the time it takes a body projected vertically downward to reach the ground and
explain the extraneous solution.
- Calculate the position and velocity at specific times for a body dropped from rest, or projected vertically downward,
or projected vertically upwards with some initial velocity.
- Perform a unit analysis for each equation presented in the Chapter Review and show that they are dimensionally correct.
- Construct and analyze position and time and speed and time graphs for both kinematics and free fall.
