Propulsion refers to the act of lifting an object into the air without movement.
b)
Propulsion is the method of keeping an object stationary in one place.
c)
Propulsion is the process of slowing down an object by reducing speed.
d)
Propulsion is the mechanism that moves an object forward by generating thrust.
21.

Why do rockets need good aerodynamics?
