analyzing projectile motion Flashcards
1
Q
initial velocity
A
incorporates projection speed (magnitude) and projection angle (direction)
-when given intial resultant velocity, break it down into the horizontal and vertical components
2
Q
horizontal velocity
A
remains constant
3
Q
Vertical velocity
A
subject to uniform acceleration of gravity (0 at apex)
sign on velocity tells direction
4
Q
Laws of Uniform Acceleration
A
formulated by Galileo
t is time to peak (formula sheet)
5
Q
for horizontal components
A
no acceleration so remove acceleration from equations
-t is total flight time
