Factors that will contribute to higher accuracy of aim when shooting a basketball into a hoop
Size of the hoop
affects the probability of shooting the ball into the hoop
with the same initial force applied, there is a higher chance of scoring due to the larger parameter needed for success.
Basketball hoop, kept constant
Initial force applied and direction
parabolic path depends on the intial velocity for (vH)
launch angle determins the maximum height, time in the air and maximum horizontal distance
types of projectile motion
Uni-level projection
lands within the same height as launch height
most likely to be focused on for the prac as it would be easier to calculate
launch height: between 1 and 1.5 meters
follows a parabolic path due to gravity
same horizontal velocity
if air reisstance is negligible
other types
ie. un uniform launch and landing heights
makes the calculations more difficult due to the different vertical distance
Mass of the ball
F = ma, the initial force depends on the acceleration given to the ball and its mass.
measure the mass using electric scale first and keep constant
Rebounds
When the ball hits the back of the board rebounds may be possible and increase chances of aim
momentum (or impulse) of the ball before and after collision with the board can be evaluated
Bounce rate of the ball
explore if bouncing the ball on the ground would increase the momentum of the ball
professional basketballers bounce the ball not only as a way to navigate the field but also increase the liklihood of shooting a goal
look into the relationship between bouncing the basketball and scoring
free fall
when air resistance equals to the force on the ball, which are opposite in direction
Risk assessments
might hit someone with the basketball
make sure to only throw the ball when there is no one in the vicinity of the basketball hoop
thrower of the ball may be injuried if thrown with improper stance
ensure the thrower is educated on how to throw basketballs (using both hands) and having the correct posture before throwing
Surface area of the ball
effects of air resistance on the ball
keep the ball constant so the surface area is the same
horizontal distance between launch and the hoop
"increased distance leads to greater spatial constraint over movements relevant to regaulating shot accuracy"

release angles
"Players should look for release angles of shooting that provide an optimal balls release velocity to im-prove accuracy."
impacts the overall horizontal distance travelled by the ball (according to formula vH = v cos (angle))
