Here is a basic simulation of jumping and gravity (using acceleration).  For block physics (falling blocks), it is very dependent on how you're rendering the blocks.  Are you re-drawing them each frame from an array or do you stamp them once in the beginning and edit them when needed?  Either way, I can tell you right now that block-physics will be quite advanced.

when gf clicked
set [y-vel v] to (0)
forever
change [y-vel v] by (-1)
change y by (y-vel)
if<touching [ground v]?>
change y by (1)
if<touching [ground v]?>
change y by (1)
if<touching [ground v]?>
change y by (1)
end
set [y-vel v] to (0)
else
change y by (y-vel)
if<(y-vel) > (-3)>
change [y-vel v] by (-1)
end

this is for the moving sprite

when gf clicked
forever
if <not<touching [the ground v]?>>
fall
end
if<<touching [ground v]?> and <key [up arrow v] pressed?>>
jump
end
end

and this is for the other one

when gf clicked
forever
if<touching [move sprite v]?>
wait (a bit) secs
fall
end
end

hope this helps

Dude,where i find the (touching ground and up pressed) thing?And about the red jump and fall thingy?

I fixed his blocks; they should be more recognizable now     The red blocks are abbreviations for whatever code you have that currently does the indicated action.  Where "jump" is, for instance, you could put this:

change y by (50)
repeat until <touching [ground v]?>
change y by (-5)
end
