It starts with the equation a=F/m. As fuel is burned, the mass of the rocket becomes less. As "m" decreases as "F" remains the same, "a" increases. There is less mass to be accelerated as fuel is consumed.
There is also less external force acting upon the rocket (No major gravity or air resistance). As Newton's first law states that an object will continue moving at the same velocity until an external force acts upon it. It would be easier to accelerate because the rocket doesn't require much fuel to generate force in space (there's no force acting upon it in the first palce)

∙ 11y agoAt greater altitudes, there will be less air resistance, less mass of the booster
as it burns fuel, and, eventually, less gravity. When those become significant,
the acceleration could increase if the force of the rocket motors remains the
same. None of this is the direct result of altitude though.

As a rocket travels upwards the engine thrust remains constant but the mass of the rocket decreases Why?
The primary answer is that a rocket under constant acceleration is using up fuel, so it's mass decreases as the fuel is spent.
Acceleration of a rocket is which type of force contact or non contact?
contact force
A ball starts at rest accelerates uniformly and travels 250m in 5 seconds What is the final velocity and the acceleration of the ball?
Average speed = (250 / 5) = 50 meters per second.Initial speed = 0Final speed = 100 m/sAcceleration = (100 / 5) = 20 m/s2===> Must be a rocket-propelled ball; its acceleration is 2G !
How do you think your bottle rocket will fly?
by water being placed into the bottle and then, when you launch your rocket, the rocket will spin (if it has at least 2 fins) and the water will spurt out and make the rocket go higher in the air. (Tip:the more it spins,the higher it will fly)

What is the intensity sound of a space rocket?
The intensity sound of a space rocket is calculated based on its acceleration and height.
Stages of a rocket going into space?
The stages of a rocket going into space: The first stage of a rocket is used to acquire the acceleration of a rocket. When the fuel of the first stage is exhausted ,it detaches from the rockets and drops off. The velocity at this stage becomes the initial velocity of the second stage .Now the second stage is ignited ,the rocket gains acceleration and it's velocity foes on increasing . The removal of the surplus mass contained in the first stage helps in attaining the higher velocity .When the fuel of the second stage is exhausted ,it too detached from the rocket .Finally at the third stage , the rocket starts off with the required velocity.

A rocket that travels 9000 meters in 12.12 seconds moves at 742.5742 meters/second which is approx 1660 mph
A rocket becomes progressively easier to accelerate as it travels upward from the ground mainly because?
The rocket's acceleration is created by the net force acting on it. There are three forces acting on the rocket: the thrust provided by the engines, gravity or weight, and air resistance. The acceleration is inversely proportional to the rocket's mass. This is Newton's Second Law: (acceleration) = (net force) / (mass) We need to think about the direction of the forces. The thrust acts upward (call this positive), and both gravity and air resistance acts downward (call these negative). So we get (acceleration) = (thrust - weight - air resistance) / mass A typical rocket engine will provide constant thrust as long as the fuel lasts. But as the engine consumes fuel, expelling the exhaust products out the back of the rocket, the rocket's mass decreases. This tends to increase the rocket's acceleration since acceleration is inversely proportional to the mass. In addition to the decreasing mass, the rocket's weight decreases as it moves farther from the center of the Earth--- this effect is described by Newton's Law of Gravity. The rocket's decreasing weight tends to increase its upward acceleration. The action of air resistance is more complicated, and ordinarily we ignore air resistance in simple models just to avoid the complication air resistance gives to the problem. In the standard air resistance model, air resistance scales with the square of the rocket's speed and the air density. The rocket is moving faster and faster, but the air density is also decreasing as it rises through the atmosphere. I think we can safely say the air resistance force decreases as the rocket gains altitude, but a detailed answer illustrating precisely how this force changes would require a numerical simulation. Hope this helps!
As a rocket travels upward from earth air resistance decreases along with gravity the rocket's mass also decreases as its fuel is used up if thrust remains the same how do these factors affect the r?
well according to newtons law the apple in the pie has fell down but went up in a triangular motion indicating that when the rocket remains constant the acceleration goes slower by oppisite forces
