2. Section 6.1
Projectile Motion
How do I separate projectile motion into horizontal
and vertical components?
How can I utilize kinematic equations to solve
projectile motion problems?
5. Projectile Motion
Projectile – an object shot through the air
Can be anything
Kinematic Equations apply
While the projectile is traveling we can draw a free
body diagram
7. From a cliff…
If I drop a ball off a cliff, what is the force acting on it?
What if I push it off the cliff?
What if I shoot it up at an angle off the cliff?
8. Gravity!
Gravity is the only acceleration in projectile motion
problems
Does gravity apply horizontally?
Is there any acceleration in the horizontal direction?
Application to equations?
11. Strategies
List Data by Horizontal and Vertical
What is the initial horizontal velocity?
What is the initial vertical velocity?
Is there a launch angle?
What is the launch height?
What is the launch length?
13. Examples
A bowling ball is rolled off a 50 m high cliff with a
velocity of 5 m/s.
How long does it take the ball to reach the ground?
How far from the base of the cliff does the ball hit the
ground?
What are the horizontal and vertical components of
the velocity just before it hits the ground?
