A model rocket, launched vertically, travels upwards 
and falls to the ground. At what point during flight is the rocket's acceleration greatest?
A model rocket, launched vertically, travels upwards
Newton's second law tells us that force and acceleration are directly related; if there is an acceleration, then there is also a force. This principle can help conceptualize this question.
While the rocket is in the air, there is only one force acting on it: the force of gravity. We can thus conclude that the acceleration of the rocket is directly related to this force. Since the force on the rocket (the force of gravity) is constant, its acceleration is also constant.
Any object that is in projectile or free-fall motion will experience a constant acceleration due to gravity.
