How is the mass of the rocket change when it lits of?
The mass of the rocket does not change, no matter what it is doing. The mass of the fuel inside the rocket will decrease as it is used up.
What is the center of mass on a Estes rocket?
How can you find the center of mass of an object like a bottle rocket?
Why do engineers need to keep the mass of a spacecraft as low as possible?
The heavier it is the stronger the engine has to be. And the stronger the engine the more fuel will it burn. And the more fuel it burns the more fuel has to be carried in the rocket. And the more fuel the rocket has to lift the stronger the engine has to be.
How does a rocket travel?
By expelling hot gasses extremely fast from the rocket nozzle. Due to the conservation of momentum, expelling mass at high velocity causes the rocket to gain momentum and therefore velocity.
How is it possible for a rocket to propel itself through space?
This is possible via the conservation of momentum. A rocket ejects matter from its back and this matter carries momentum. To conserve momentum the rocket must gain an equal amount of momentum in the opposite direction. Since momentum is related to velocity this causes the rocket to move. This is basically an application of Newton's third law. You might have been confused with the situation in air. For example an airplane moves through air by pushing air past it (using its propeller). This accelerates the air, and thus increases its momentum. The airplane must therefore gain momentum in the opposite direction, and accelerates itself as well. The only difference between the airplane and the rocket is that the rocket carries the stuff it accelerates (and ejects) while the airplane can use the air that is already present all around it. Note that while this is the basic explanation, the situation with the rocket is made somewhat more complicated by the fact that as the rocket loses fuel it also loses momentum because momentum is velocity times mass and the lost fuel lowers the mass of the rocket. You might want to look up Tsiolkovsky's rocket equation if you want more information.
Why is the mass of the rocket payload so important when launching a rocket to the moon?
The greater the mass of the payload, the more fuel (and more money) it requires to get it into orbit.
How is the mass of the rocket change when it lits of?
The mass of the rocket does not change, no matter what it is doing. The mass of the fuel inside the rocket will decrease as it is used up.
What is the difference between model rockets and real rockets?
In a real rocket, there is short a time in atmosphere and the aerodynamics are less important. In a model rocket, all flight in the atmosphere and the aerodynamics are very important. In a real rocket, it has a liquid or solid rocket engine and a large propellant mass fraction. In a model rocket, it has a solid rocket engine and a small propellant mass fraction . In a real rocket, there are four forces during atmospheric flight. In a model rocket, there are four forces throughout flight. In a real rocket, there is a long powered flight . In a model rocket, it has a very short powered flight . In a real rocket, it has passive stability and active control . In a model rocket, it has passive stability and no control. In a real rocket, it has expensive materials such as aluminum, titanium, and nickel alloy. In a model rocket, it has inexpensive materials such as balsa, cardboard, and plastic. In a real model, there is a high speed and the heating is very important. In a model rocket there is low speed and the heating is not important.
What is the center of mass on a Estes rocket?
How can you find the center of mass of an object like a bottle rocket?
Where should the center of mass be located on a rocket?
near the nose of the rocket
A force of 1500 N gives a rocket an acceleration of 2.5ms2 what is the mass of the rocket?
it is 600kg
What happens to the weight of a rocket when it takes off?
The mass of the rocket decreases as fuel burns.
Does the escape velocity of a rocket depend on its mass?
no
Does a rocket works on principle of conservation of mass?
No
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.
Why do engineers need to keep the mass of a spacecraft as low as possible?
The heavier it is the stronger the engine has to be. And the stronger the engine the more fuel will it burn. And the more fuel it burns the more fuel has to be carried in the rocket. And the more fuel the rocket has to lift the stronger the engine has to be.
What purpose does water serve in a water bottle rocket?
Water serves as the reaction mass in a water bottle rocket. When the water is pressurized and released, it creates the thrust that propels the rocket into the air. Additionally, the water helps to stabilize the rocket by shifting its center of mass downward as it is expelled.
