Type I Type II
Any object that has been given an initial thrust, then moves only under the force of gravity.
The path of a projectile is called the trajectory
The motion of the object is in two directions (1st time)
To solve projectile motion problems, solve all variables individually
The motion of a projectile in the “X” direction is independent of the motion in the “Y” direction
doesn’t effect vertical
Type I Animation
(watch magnitude of velocity arrows)
“X” direction“Y” direction
dx = vx x t dy = ½ gt2
vx = dx / t vfy = g x t
Proof that motion is independent
