For every action, there is an equal and opposite reaction. Sample case me doing a push up I force myself to move up by pushing against a rigid body (the floor).
There goes I can not push myself sideways by thrusting my hands forward but as the case of a pushup. Or if I hit the water with an open fist it feels painful because the movement causes the liquid to feel like a rigid body (instantiating rapid opposing motion on a body).
So with that, moving to rockets, their motion (in earth) is caused by a heavy surge of air simulating the hard body (with the open fist slap on water logic) and when enough causes the rocket to move in the other direction.
My current logic in this argument is for the opposite reaction to occur, there is an opposing opposite matter that causes makes the opposite reaction to recache in the other direction?
As I am trying to understand how something would move in a vacuum. In the case of a bird also it pushes air down for it to go up... My mechanical physics is not that great I am tackling this in a more logic-based approach.So, a case scenario definition of all the definitive forces and direction of reaction would be well appreciated and is this logic correct (for a motion to occur there must be something resisting movement).
