An object will accelerate in free fall because the only force acting on it is gravity. true or false.

The conclusion is true, but I'd reach it in a slightly different way:

- - An object in free fall is acted on by only the force of gravity.

- - Since there's only one force on it, the forces can't be balanced,

and the net force on it can't be zero.

- - Since the net force on an object in free fall can't be zero,

such an object will always accelerate.
