analyzing projectile motion

Question 1

initial velocity

Answer 1

incorporates projection speed (magnitude) and projection angle (direction)
-when given intial resultant velocity, break it down into the horizontal and vertical components

Question 2

horizontal velocity

Answer 2

remains constant

Question 3

Vertical velocity

Answer 3

subject to uniform acceleration of gravity (0 at apex)
sign on velocity tells direction

Question 4

Laws of Uniform Acceleration

Answer 4

formulated by Galileo
t is time to peak (formula sheet)

Question 5

for horizontal components

Answer 5

no acceleration so remove acceleration from equations
-t is total flight time
