*** To understand this type of motion we must breakup the velocity into
horizontal and vertical parts (components)

Finding Horizontal & Vertical Components (parts)





Initial Horizontal
Component of Velocity


Vix = VcosӨ
(on reference table)




Initial Vertical
component of velocity


Viy = VsinӨ
(on reference table)

Ex) Which angle of projection causes a projectile to stay in the air longer? 

 50 or 70 degrees?


70 degrees,

(closest to 90,
longer time in air)
