- Discuss the trajectory of a projectile in the earth's gravitational field.
- Define scalar and vector and give examples of each.
- Determine the x and y-components of a given vector by graphical methods.
- Define vector sum and resultant of two or more vectors.
- Use the Triangle Method and the Parallelogram Method to find the resultant of two vectors.

- Calculate the x and y-components of a given vector.
- Calculate the magnitude and the direction of a vector when its rectangular components are given.
- Calculate the resultant of two or more vectors using the Component Method.
- Give a graphic illustration of vector difference.
- Illustrate an understanding of relative motion in one and two dimensions.
- Illustrate graphically how the motion of a horizontally projected baseball compares with that of a baseball dropped from
rest.
- Illustrate with diagrams how the vertical motion of a baseball thrown at any angle is similar to the motion of a baseball
thrown vertically.
- Predict the position and velocity of a projectile as a function of time when the projection angle and initial speed are
given.
- Predict the range, maximum altitude, and time of flight for a given projectile when the initial speed and the angle of
projection are given.
