As a rocket ascends, its acceleration increases even though the net force on it stays constant. Why? (Assume a traveling distance small enough that the thrust, acceleration due to gravity and atmosphere do not change.)
As the rocket ascends, fuel is burned at a faster rate resulting in a larger acceleration.The rocket's mass decreases as its fuel is consumed. The same net force acting on a smaller mass results in a larger acceleration. The faster a rocket moves the more acceleration is imparted to it from a given force.As a rocket ascends its momentum increases with its speed. The greater the momentum of the rocket, the greater the acceleration imparted to it from a given force.

making holes in hard rock so explosives
