Ok, so what cause the damage if not some energy conversion, is it the momentum ? I know I heard on TV, they always say something hit something with a force of blah. I never heard they said impact with momentum of blah or energy of blah. Don't give me up on yet.

So even though the bullet does not have any force, it has momentum and energy and when it hits another object, this energy somehow converts pack to force at impact. Thanks, I am glad you told me, I was going to jump in front of the bullet to prove an experiment.

It has been awhile since I took Physics. The other day my daughter asked some questions about force. She told her teacher explained if the object is moving horizontal the push force is 0. I said that can't be right. There has to be a force to overcome friction. This lead me thinking...
