projectile motion

Question 1

what is a projectile

Answer 1

an object moving through the air and accelerating due to gravity

Question 2

describe important features including, x and y components

Answer 2

-gravity influences vertical motion
-horizontal motion remains constant
-result in parabolic trajectory

x and y components are perpendicular therefore independent

Question 3

aspects of x component

Answer 3

no net force
-constant motion
-acceleration is always 0
-only equation used is Vx=dx/t

Question 4

what is the only value used on both x and y sides

Answer 4

time(scalar)

Question 5

what are the two types of projectile motion

Answer 5

1. horizontal projectile motion ( no initial vertical velocity)
2. projectile motion at an angle ( with initial vertical velocity)
