horizontal component projectile motion projectile vertical component resolving a vector vector scalar addition of vectors Chapter 3 Objectives:

When you have completed Chapter 3, you should be able to:

1. ... describe the difference between vector and scalar quantities.
2. ... add two perpendicular vectors graphically or analytically.
3. ... find the horizontal and vertical components of a vector.
4. ... find the magnitude and direction of a vector given its horizontal and vertical components.
5. ...describe the motion of a projectile launched horizontally in terms of the horizontal and vertical components of the motion.
6. ...calculate the range and time of flight of a projectile launched horizontally.
7. ...describe the motion of a projectile launched at some angle to the horizontal in terms of the horizontal and vertical components of the motion.
8. ... state that the maximum range for a projectile will be achieved at a launch angle of 45o to the horizontal.
9. ... recognize that a projectile launched at an angle to the horizontal will have the same range as a projectile launched at the angle 90o - .
10. ... discuss the relationship between satellite motion and projectile motion.

Possible Preconceptions to Correct

Here are some misconceptions about Projectile Motion that you may need to correct:

• Wrong: The curved motion of a projectile is very different from common one-dimensional motions.
• Wrong: The horizontal speed of a projectile decreases as the projectile moves.
• Wrong: An object will fall straight to the ground faster than an object initially moving horizontally will fall from the same height.
• Wrong: At the top of its trajectory, the velocity of a projectile is always momentarily zero.     last update October 3, 2008 by JL Stanbrough
