need this for a project im working on

Could you please explain further on what you want help with? Maybe a link to the project?

So, there's a few ways to do this, though they differ.

1. Moving the sprite

when green flag clicked
set [velocity v] to [20]
if <[0] < (velocity)> then
point in direction ( whatever v)
move (velocity) steps
change [ velocity v] by (-0.05)
end
bounce

2. Bouncing

define bounce
if <touching [ rectangle v] ?> then
turn ccw (180) degrees
set [ velocity v] to ((velocity) + (1))
repeat (10)
move (velocity) steps
change [ my variable v] by (-0.05)
end
end

3. Example project



This isn't highly polished, but it's a nice start that everyone can hopefully modify.

Good luck and keep scratching!

Note that turning 180 degrees is not a sensible way to bounce - it only makes sense if the moving sprite approaches the surface it is bouncing off at an angle perpindicular to that surface. Imagine playing pool/snooker if the ball always bounced off a cushion back towards you!

A realistic bounce depends on both the approach angle and the angle of the surface as shown here https://scratch.mit.edu/projects/99412537

ya this would not work (he made me waste 5min trying to figure out y it wasn't working

does not work

There's a great griffpatch video about bouncing physics. I recommend you check it out.

this does NOT work don't try it (if you do then you will waste soo much time)

(pick random () to (10))

oh my God I almost feel bad for this guy he's got nothing but hate comments

me too

There are several posts offering help so I don't see how you interpret things that way!
