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.
What is the Effect of increasing the object's mass of the acceleration due to gravity?
On earth, the mass of an object has no effect whatsoever on its acceleration due to the force of gravity. All objects fall with the same acceleration, regardless of their mass. Any observed difference is due entirely to air resistance.
What is the force that accelerates a rocket called?
The combustion of rocket fuel ejects a mass of material at high velocity. In accordance with Newton's third law, the momentum of the ejecta generates an equal and opposite reaction - which propels the rocket forward.
How does the mass of an object effect acceleration?
Take a look at Newton's Second law, usually written as: F = ma Solving for acceleration: a = F / m In other words, other things (the force) being equal, more mass means less acceleration.
Does force describe mass or acceleration?
Neither. Force causes acceleration of mass. Mathematically, Force = Mass * Acceleration.
A force of 1500 N gives a rocket an acceleration of 2.5ms2 what is the mass of the rocket?
it is 600kg

How does size effect accelaration?
Size affects acceleration in terms of mass. If the size or mass is bigger, acceleration will be lower and vice versa.

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!
What happens to acceleration of an object if the force on the object stays the same as its mass decreases?
It increases. (Standard rocket science.)

How do you improve accelaration of a rocket in space?
F = M A whence A = F/M .Acceleration is directly proportional to the force applied to the rocket, and inverselyproportional to the rocket's mass. If you need to increase the acceleration, you havetwo choices . . . either reduce the rocket's mass, or increase the force applied to it.That means you must either toss something overboard, or else burn fuel faster.There's no other way.

Why does a rocket takes a lot of force?
A Rocket has a LOT of MASS. Its initial Velocity is ZERO and its final velocity must be approximately 25,000 MPH to get into Orbit. That takes a LOT of Acceleration! FORCE = MASS x ACCELERATION FORCE = 1/2 MASS x V2 (the 2 means squared) Looking at these equations you can see that requiring a High amount of Acceleration, and a LARGE terminal Velocity acting on a HUGE Mass, will require a "lot of FORCE". It is simple Arithmetic!
What forces cause a rocket to fly?
look mass times acceleration equals potential gravity this causes rockets to launch
What does mass mean in weighing?
The weight is the mass multiplied by the acceleration of gravity. When weighing an object by a balance the acceleration of gravity is on both sides of weighing and hence canceling its effect and hence you get the object mass (not the weight)..
