Angle of release affects
the consequent parabola of the object
the velocity of the object
the accuracy of the parabolic arc
the athlete's ability to strike the center of percussion
If the timing of the summation of force is early, the object will
be struck with maximal force and travel the maximum distance
be struck before maximal force has been achieved and consequently not travel as far
go just as far as if it had been struck at the perfect time or late
get to the party earlier
The flight path of a frisbee would be described as
rectilinear motion
rotational force
curvilinear motion
movement in any plane
Tilting your head forward is an example of
a first class lever
a second class lever
a third class lever
a dance move
A second class lever is classified as
a "speed multiplier" because it has a longer resistance arm that requires greater force to move a load
a "force multiplier" as it has a shorter lever and therefore makes it easier to move a heavy object with less force by increasing the distance over which the force is acting
the head tilt lever
the one without a fulcrum through which to pivot
A third class lever is classified as
the best for creating projectile motion
a "force multiplier" as it makes it easier to move a heavy object as it increases the the distance over which the force is acting
a "speed multiplier" as it has a long resistance arm that requires greater effort to move a load
the bicep curl lever
When handballing an AFL ball, which 3 factors will determine the distance of the projectile motion
The size of the fist
The angle of release
The height of release
The power generated through the bicep femoris and gastronemius
The speed of release
Which two factors affect the trajectory of an object when in motion
push and pull
gravity
projectile motion
drag
Angle of release impacts which two types of velocity?
vertical
horizontal
rectilinear
curvilinear
Height of release matters when kicking an AFL ball from the ground because
when a projectile is released from a point equal to the landing height, the optimal angle of release for maximum distance is 45 degrees
when the projectile is released from a point higher than the landing height, the optimal angle of release for maximum distance is 75 degrees
when the projectile is released from a point lower than the landing height, the optimal angle of release for maximum distance is 40 degrees
when the projectile is struck from the ground, the angle of release doesn't matter
