9 Projectile Motion

Question 1

involving objects thrown/projected into the air

Answer 1

projectile motion

Question 2

projectile motion’s horizontal and vertical motions can be best described as…

Answer 2

horizontal - constant motion
vertical - constantly accelerating motion

Question 3

object thrown in projectile motion

Answer 3

“projectile”

Question 4

range

Answer 4

Δx

Question 5

height

Answer 5

Δy

Question 6

path of a projectile; typically parabolic (in cases where air resistance is ignored)

Answer 6

trajectory

Question 7

total time of flight for a projectile

Answer 7

time of flight

Question 8

angle between the initial velocity and the horizontal axis

Answer 8

angle of projection (θ)

Question 9

does horizontal velocity impact the time a projectile takes to reach the ground?

Answer 9

NO.
horizontal velocity only affects range

Question 10

do projectiles launched from complementary angles with the same launch height and initial velocity have the same range?

Answer 10

YES.
only the maximum height is different; greater θ = greater height

Question 11

maximum range is achieved at what θ?

Answer 11

45 degrees
