A model rocket is launched vertically upwards. After its engine burns out, it continues to move upwards before falling back to the ground.
Neglecting air resistance, what effect does the force of gravity have on the rocket's acceleration after the engine burns out?
It produces a constant acceleration downwards throughout the remainder of the flight.
It produces a constant acceleration upwards while the rocket is moving upwards.
It produces an increasing acceleration downwards as the rocket falls.
It produces zero acceleration at the highest point of its path.
