Projectile Motion Flashcards

Question	Answer
Air resistance Definition	"A frictional force that opposes motion (producing a deceleration) due to an object moving through air particles
Projectile Motion Definition	"a motion that can be separated into a two component motion, a horizontal component travelling at constant velocity and a vertical component travelling at constant acceleration forming a parabolic path"
Constant Velocity in horizontal	no ΔV horizontal >no a horizontal >F=0 a=(∆V )/t F=ma a∝ ∆V F∝ a To show constant velocity reverse above sequence, from no F horizontal (ignoring air resistance)
Vertical velocity component	changing vertical velocity due to different lengths of vertical vectors on diagram ∴ ∆V (∆Vi = Vf - Vi) ∴ > a (a=(∆V )/t) a∝ ∆V ∴ >F (F=ma) F∝ a As F vertical (F due to gravity) > a > ∆V ∴ changing velocity
