Objectives
1. Explain the difference between vector and scalar quantities and give examples of each.
3.2 Velocity Vectors
2. Draw vector diagrams.
3. Use the graphical method to find the resultant of two vectors.
Vector Trigonometry Class Notes
4. Determine the resultant of two vectors at right angles using trigonometry.
3.3 Components of Vectors
5. Given a vector, resolve it into horizontal and vertical components.
Vector Trigonometry Class Notes
6. Determine the resultant of two vectors that are not at right angles using trigonometry and
the vector resolution method.
3.4 Projectile Motion; 3.5 Upwardly Launched Projectiles
7. For a projectile, describe the changes in the horizontal and vertical components of its
velocity, when air resistance is negligible.
8. Explain why a projectile moves equal distances horizontally in equal time intervals, when
air resistance is negligible.
Class Notes on Projectile Motion
9. Solve problems involving projectile motion for projectiles fired horizontally and projectiles
fired at an angle.
3.5 Fast-Moving Projectiles - Satellites
10. Define satellite and explain it's motion.
Misconceptions
Note: The following statements are all FALSE!!!
1. 1 + 1 = 2 always.
2. The curved motion of a projectile is very complicated.
3. An object at rest will drop to the ground faster than the same object moving horizontally at
high speed.
4. At the top of its trajectory, the velocity of a projectile is always momentarily zero.
