In a spaceship far from the reaches of gravity, under what conditions could you feel as if the spaceship were station- ary on Earth’s surface?

constant acceleration of 9.81 m/s^2 against the weight of the person standing in spaceship.

Explanation:

- At earth surface we would feel a gravitational pull of g = 9.81 m/s^2 downwards.

- For anyone on spaceship to feel the same pull the spaceship needs to accelerate upwards at a constant acceleration of a = 9.81 m/s^2.

- The effect of "weightlessness" is removed such that the contact force between the person on the space-ship and the person him or herself is equal to the apparent weight of the person.

- If the spaceship accelerates constantly at 9.81 m/s^2,  the apparent weight of the person would equal the actual weight on earth.
