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.

When is velocity antiparallel to acceleration?
when a ball is thrown upwards velocity increases but acceleration decreases hence making it anti parallel to each other
A bullet traveling upwards has what type of energy?
it has both potential and kinetic energies as when it is going upwards, the potential energy increases while the kinetic energy decreases until it reaches the top, and then the kinetic energy is zero and the potential energy is maximum.
When tossing a coin upwards what happens to its velocity while ascending what happens to its acceleration?
Its velocity decreases because gravity is pulling on it as it goes up. Its acceleration increases.
Why does the total weight of the shuttle decrease in the first 20 seconds?
its weight decreases since most of that weight is fuel and is being burnt off to get lift
What is the equations of motion for an object thrown vertically upwards?
You can any of several formulae for constant acceleration, found in any physics textbook. Acceleration due to gravity is about 9.8 meters/second2.
As you rise upwards in the atmosphere air pressure?
it decreases
As you go upwards from the Sun's photosphere?
temp decreases
Which direction do fires normally travel?
it travels up
Why can you smell the dinner cooking from upstairs?
Because the air (gas) has a low density, it travels upwards.
What happens if your density is lighter than the density of air?
you will start to float upwards in the atmosphere. The density of air decreases as you go higher in the atmosphere. You will stop going upwards when you reach a height where the air density is the same as your density.
When is velocity antiparallel to acceleration?
when a ball is thrown upwards velocity increases but acceleration decreases hence making it anti parallel to each other
Do phloem travel up or down?
the xylem transports water upwards and and the phloem transports food downwards in a plant .
A bullet traveling upwards has what type of energy?
it has both potential and kinetic energies as when it is going upwards, the potential energy increases while the kinetic energy decreases until it reaches the top, and then the kinetic energy is zero and the potential energy is maximum.
Where is the aorta?
The aorta is the main artery leaving the heart. It begins at the top of the left ventricle and travels upwards before splitting into smaller arteries.
When tossing a coin upwards what happens to its velocity while ascending what happens to its acceleration?
Its velocity decreases because gravity is pulling on it as it goes up. Its acceleration increases.
How does carpet prevent heat loss?
carpet has fine fibres in it. heat travels upwards so when it does the carpet fibres traps the heat. The thicker the carpet the better.
What names of the tubes and the process that bring water up a plant?
stems but inside the stems are two tubes! the one that travels water upwards is called xylem!
