Josh - what specific question do you have about those questions? #5 - moves lower #12 notes on projectiles - what do I want the ball to do? #16 - water or air #20 - Blog post from a mini lab we did
On the Fluid Dynamics Cont. note sheet you gave us, it says topspin restricts horizontal movement, and backspin increases horizontal distance. Will you explain this please?
what is the difference between profile drag and skin friction drag?

Skin- the surface of the object (fuzzy tennis ball); profile is form or body position

ReplyDeleteThe spin on a ball with topspin makes the ball move down, backspin goes up. Go back to the notes you drew from the back board with the arrows.
DeleteWhy is the pitcher's mound raised?
ReplyDeleteIt makes the take off point higher than the landing point. Look in notes as to how that changes velocity. think of gymnasts sticking a landing
