Projectile motion

Question 1

factors affecting the horizontal displacement of a projectile

Answer 1

angle of release
speed of release
height of release

Question 2

angle of release

Answer 2

the optimal angle of release is dependant on release height and landing height. 45*

if release height is lower than landing height, then the optimal angle of release need to be greater than 45 degrees (shooting a basket)

if the release height is greater than the landing height, the OAR needs to be less than 45* (shot put 26-38*)

Question 3

speed of release

Answer 3

the greater the velocity of a projectile, the greater the horizontal displacement travelled.

Question 4

height of release

Answer 4

a greater release height results in a greater horizontal displacement

Question 5

factors affecting the flight paths of different projectiles

Answer 5

weight
gravity
decide whether a projectile has a flight path that is a true parabola or a distorted parabola (symmetrical curve on a graph)

projectiles with large weight force have a small air resistance force and follow a true parabolic flight path
e.g. shot put

the longer the flight path, the longer air resistance can affect a projectile

Question 6

horizontal component

Answer 6

the horizontal motion of an object

Question 7

vertical component

Answer 7

the upward motion of an object
