There are a lot of way to make a bouncing ball, this is a fast and easy way.
1) Build a sphere in according with my [A ref.] and move it so that bottom point is on zero (x=y=z=0) [B ref.]
2) Build an effector in zero (x=y=z=0) and then link the sphere to effector [B2 ref.].
3) Selected sphere and open link window, setting pivot point at bottom [C ref.] and enable "inherit scale" [D ref.].
4) Select the effector, add keyframe and move effector at last position. (This is the orizontal component of motion).
5) Open project window, toggle on frame display then search "Position" channels of effector.
6) Select all cells of y channel and set a jolt vibe effect with my data [E ref.] (This is the vertical component of motion). The problem is that this last value change from negative to positive value, we can rimediate.
7) Select all cells of y channel and set a fill constant vibe effect with value @# [F ref.]; this transform every values with absolute values.
8) Search "Y scale" channel of sphere, select all cells of y channel and set a jolt vibe effect with my data [G ref.]. This is a the ball deformation.
9) Copy every value of "Y scale" channel of sphere, fill entire channel with 1.0, select frame to 3th at last frame then paste your "scale data". This is right delay of physics effect.
10) Try your animation.
