##### How would you calculate the force felt during acceleration?

Say we have an object being accelerated towards a gravitational source. Where the applied acceleration is 2 * g where g is the gravitational acceleration. Then firstly would the force of acceleration be felt and secondly what value of g would actually be experienced by the accelerated object? How would this be calculated?

Let's assume that the acceleration is in same direction. Then the external force causing the body to fall at a rate of 2g will be felt by observers inside as 2g as well. When the gravitational solurce is added it will decrease this acceleration by 1g making the observer feel and acceleration of 1g.

Thanks Pete that is what I thought I just wanted it confirming.
