[MCU] so does Cap’s shield absorb energy or not?

So in Winter Soldier he falls 30 stories and uses the shield to break his fall. So it seems to absorb energy. But when he throws it it bounces all over, almost increasing in energy. And when Thor hits it with his hammer in Avengers it deflect energy everywhere. What is it supposed to do?

It can both store and release energy. Think of it as a less refined version of Black Panther’s suit. 

BP absorbs energy and can release it as a shockwave. He has more control over the release than Cap does with his shield, but he does have to release the energy if it’s too much. Thor swinging Mjolnir onto the shield was too much energy to store so it released as a shockwave. A bullet hitting it is not. 

There’s also evidently a difference in composition from the center of the shield which seems to have more Vibranium and the edges since the edges have more bounciness to them.
