The students were asked to get out their lab notebooks and worksheets as they would debrief their projectile motion lab from Monday and practice their understandings. Specifically, they would discuss how increasing the initial velocity of a projectile affects its path, with a higher initial speed resulting in a greater horizontal distance traveled, known as the projectile's range, before falling due to gravity in the vertical direction.

1. Good Morning!
Please DO NOW:
 pick up your lab notebook
 pick up a copy of PTG 2.4 (a
worksheet)
 sit down and get out a pen or pencil
Today we will:
 “de-brief” the lab from Monday
 practice our new understandings

2. Projectile
Motion
How does initial
velocity affect the
path of a projectile?

3. Initial Velocity
As we learned Monday, initial
velocity has no effect on the
“hang time” of ANY projectile.
That doesn’t mean initial
velocity has NO effect on
anything, however.

4. How does initial velocity affect
the path of a projectile?
 What do you think? Think back to
when you varied the speed of the
aquarium stone with the launcher.
What effect did increasing the
speed have?

5. How does initial velocity affect
the path of a projectile?
The greater the initial horizontal
speed, the farther the projectile will
travel.
We call this distance in the x “range”
Range: the distance a projectile
travels in the x direction
What motion would happen in the y?
