What is the difference between the words vertical and horizontal?
What does the word projectile mean?
How is one dimensional (1D), two dimensional (2D), and three dimensional (3D) different?

2. What is Projectile Motion?

3. Projectile Motion Two-dimensional motion of an object Vertical
Horizontal

4. Types of Projectile Motion
Horizontal
Motion of a ball rolling freely along a level surface
Horizontal velocity is ALWAYS constant
Vertical
Motion of a freely falling object
Force due to gravity
Vertical component of velocity changes with time
Parabolic
Path traced by an object accelerating only in the vertical direction while moving at constant horizontal velocity

5. Examples of Projectile Motion
Launching a Cannon ball

7. Equations
X- Component
Y- Component
Vectors
Note: g= 9.8 m/s2

8. Factors Affecting Projectile Motion
What two factors would affect projectile motion?
Angle
Initial velocity
Initial Velocity
Angle

9. Range of a 2-D Projectilex y
Range
Definition: The RANGE of the projectile is how far it travels horizontally.

10. Maximum height of a projectiley
Maximum
Height
Range
The MAXIMUM HEIGHT of the projectile occurs when it stops moving upward.

11. Maximum height of a projectiley
Maximum
Height
Range
The angle and initial velocity affects the range and maximum height a projectile achieves.

12. Projectile Motion Formulas

13. EXIT TICKET A= ______ V= ______ A= ______ V= ______ V= ______
V= 30 m/s
V= ______
A= ______
A= ______

14. Class Exercise
An object is fired from the ground at 100 meters per second at an angle of 30 degrees with the horizontal
Calculate the horizontal and vertical components of the initial velocity
After 2.0 seconds, how far has the object traveled in the horizontal direction?
How high is the object at this point?
