PROJECTILE MOTION: INTRO & SYMMETRIC LAUNCH. ○ Projectile Motion occurs when an object is launched and moves freel
PROJECTILE MOTION: INTRO & SYMMETRIC LAUNCH ● Projectile Motion occurs when an object is launched and moves freely in 2D space. - Remember that the first step in any 2D Physics problem is to ____________________ it into X & Y components. - When decomposing vo, vox goes with the ____ motion, voy with the ____ motion (vo no longer useful). - So Projectile Motion is _______________ motion WITH _______________________ horizontal motion (ax = 0). - These “two” motions (X & Y) are ___________________ & _____________________ (same ____). - Remember: If YA = YC, then A & C are __________________  (1) ______________ and (2) ______________. - At any point, the object’s velocity vector is _________________ to its path. aX = ____  ____ Equation(s): vAx = _____ = _____ = _____

aY = ____  ____ Equation(s)  For every question:

(1) Determine AXIS (X or Y)

(2) Pick an INTERVAL

(3) Pick an EQUATION

EXAMPLE: An object is launched from the ground with 50 m/s at +37o, and later returns to the ground. Find its: (a) Maximum height (b) Time to reach max. height (c) Total time of flight (d) Horizontal displacement (range)

● Symmetric launches attain max range when Θ = ____. Complementary angles (eg. ____ & ____) attain the same range.
