1. LIFT: Back Spin LIFT: Top Spin Bottom of ball moving toward the direction of the ball’s flight lower flow on bottom higher flow on top F LIFT UPWARD Top of the ball moving toward the direction of the ball’s flight lower flow on top higher flow on bottom F LIFT DOWNWARD

2. Back Spin Ball Drops @ an  to floor

3.  Bottom of ball moving toward flight direction  Ball has both horizontal and vertical motion  ball spin rubs floor in a horizontal direction that decelerates the ball’s forward motion  Result =  horizontal  vertical motion   Rebound  is higher than drop 

4. Top Spin Ball Drops @ an  to floor

5.  Top of ball moving toward flight direction  Ball has both horizontal and vertical motion  ball spin rubs floor in a horizontal direction that accelerates the ball’s forward motion  Result =  horizontal  vertical motion   Rebound  is lower than drop 

6. Back Spin Basketball Bank Shot

7. Backboard is on a vertical plane Ball Drops @ an  to board with Back Spin same reaction as a top spin ball off floor

8. Different View of Backboard Ball coming into backboard with top spin

9. Side Spin Ball Hits Straight On

10. Lateral spin pushes horizontally against wall/rail a reaction force in the opposite direction of the spin ball rebound  is in the direction of the reaction force
