## Conceptual Physics (12th Edition)

If the spaceship accelerates at a rate of $g = 9.8 \frac{m}{s^{2}}$, you would feel that you were in a stationary ship at Earth's surface. A less satisfactory answer is that if your spaceship were to rotate to cause a centripetal acceleration of $g = 9.8 \frac{m}{s^{2}}$, you would feel that you were in a stationary ship at Earth's surface. However, in the latter case, depending on the radius of curvature of your motion, different parts of your ship might feel wildly varying local values of acceleration.
