Energy and Forces 
Newton's Laws
First Law
-
-
-
-
:pencil2: There has to be some sort of force to make the rocket accelerate. Otherwise, it will remain at rest.
Second Law
-
-
if unbalanced force is against object, it causes decceleration
-
Third law
when object releases force on another object, the other object releases equal and opposing force on first object
-
:pencil2: The rocket will exert the same amount of force as the pump. So, we need to pump the rocket with a desired force that would be safe.
