1. Projectile Motion
Chapter

2. Projectile Objects that follow a curved path near the surface of Earth
Examples:
cannonball shot from cannon
Object rolling off edge of table

3. Horizontal Motion of Projectile
Same as motion of object along level surface
When you ignore friction,
object moves at a constant velocity
Object moves equal distances in equal time intervals

4. Vertical Motion of Projectile
Same as free falling object
Acceleration= gravity
Speed changes by 10 m/s each second
Distance an object falls each second still d=1/2gt2

5. The horizontal and vertical components of motion of a projectile are completely independent.

6. Upward Launched Projectiles
Horizontal component is constant
Vertical component changes by 10 m/s due to gravity

7. Practice Problem: A boy stands on a 5 m tower and throws the ball
Practice Problem: A boy stands on a 5 m tower and throws the ball. The ball travels 20 m before hitting the ground. At what speed was the ball thrown?

8. Satellites
Projectile traveling fast enough to fall around Earth rather than into it
Speed of 3-8 km/s.
