Question

A rocket will move upward as long as the thrust is greater than the force of gravity. Please select the best answer from the choices provided T F

Answer 1

The statement seems somewhat intuitively satisfying at first.  But upon
closer inspection, we must admit that it's too sloppy to be called 'True'. 
Self respect and academic integrity compel us to mark it 'False'.

A rocket will accelerate upward as long as the thrust is greater than
the force of gravity AND is directed upward.

Furthermore, imagine a rocket that is falling, buttocks-first, when the
engines ignite and generate a thrust force that is greater than the force
of gravity.  Some time will pass before the rocket stops falling and starts
rising.
