Thrust is the force that propels a rocket or spacecraft and is measured in pounds, kilograms or Newtons.
Gravity
If you mean do any manned spacecraft use artificial gravity, the answer is, not so far. But, in the future, large spacecraft may create artificial gravity by rotating them. To conserve fuel, the gravity of the moon/planets is used to pull spacecraft toward them. And of course the gravity of earth is used to hold/pull on spacecraft so they orbit (circle) around it instead of flying off into space.
I think its your reflection
Unfortunately, the answer which [I think] is required is incorrect.I expect that the answer that you are required to provide is Newton's law of Inertia. A part of this states that a body in motion remains in constant motion in a straight line unless it is acted upon by an external force. However, there are very few place in space where this can happen. Even at points in space where the gravitational force of the Sun is exactly matched by that of the Earth, as soon as the spacecraft moves from that point, the forces will be in imbalance and the spacecraft will experience an external force which will affect its speed.
Front off side
There are about four forces that act on a lifting off spacecraft . The four forces are the thrust force, the weight of the spacecraft, the drag and the lift force.
The forward momentum forces you back.
There are various forces acting on them, but a few forces which significantly decide their motion are: 1. On moon: Gravitational force due to earth and sun 2. On spacecraft: Gravitational force due to earth, moon and sun
One reason why landing a spacecraft on the moon takes careful planning is that the moon move along its own path (its own orbit).One reason why landing a spacecraft on the moon takes careful planning is that the moon always moves along its own orbit.

It takes about 3 days for a spacecraft to reach the moon. During that time a spacecraft travels about 240,000 miles (386,400 kilometers) which is the distance between Earth and the moon.

A spacecraft take off by using 3 boosters to get it into space. It comes back just using the spacecraft and landing it near a station.
