squash and stretch are in the same direction and usually from top to bottom… squash is the compression of (for example) a sphere from top to bottom making it’s center (equator) bulge out, stretch is the opposite of that from top to bottom it gets longer making it’s center go inward… but the movement is still best thought of as vertical direction…
so squash happens as the sphere is landing on the ground (being compressed) and stretch happens when it jumps off the ground
hope this helps
