Module 3

Question 1

What are projectiles?

Answer 1

flight patterns of objects are normally consistent
usually predictable when thrown

Question 2

What is Bernoulli’s principle?

Answer 2

an object will always want to move in the area of least resistance or lesser air pressure rather than more pressure.
- pressure is inverse to the speed of the fluid

Question 3

What is the Magnus Effect?

Answer 3

a moving projectile with topspin will create high pressure on top and lower pressure on the bottom, making the object fall faster than without spin
the pressure differential causes the path of the ball to move from the area of high pressure to the are of lo pressure.

Question 4

spinning objects and body

Answer 4

an object can spin faster than a body
humans can’t move fast enough for the Magnus effect to come into play

we can speed up our rotation by bringing our limbs closer to our COG to gain rotational speed.

Question 5

Flattening of the swinging arc

Answer 5

changing the path of the swing of the object so you have more chances to release it in the right direction.
can be done by taking a step, or extending your arms to flatten the swing

Question 6

What are 5 techniques used to flatten the arc?

Answer 6

rotating the body
weight transfer
bending your front leg
sequential body movement
utilizing a follow through.
