What else can I help you with?
When a rocket lifts off it's upward momentum is matched by the downward momentum of?
the expelled exhaust gases, which follow Newton's third law of motion - for every action, there is an equal and opposite reaction. This creates a reaction force pushing the rocket upward, allowing it to lift off.
What is does momentum have to do with bottle rockets?
When it comes to water bottles, there is downward momentum, which creates an upward momentum. The reason for this is the conservation of momentum. That's why the water bottle is driven upward. The downward momentum is created by the water mass times water's velocity.
When a rocket lifts off the ground the net force is in upward direction. Is the upward pushing force greater or lesser than the downward pull of gravity.?
Greater
What two forces are acting on a rocket when it takes off?
The two main forces acting on a rocket during takeoff are thrust, which propels the rocket upward, and gravity, which pulls the rocket downward.
When a rockets lifts off the ground the net force is in an upward direction Is the upward pushing force greater or lesser than the downward pull of gravity?
When a rocket lifts off the ground, the upward pushing force (from the engines) is greater than the downward pull of gravity, allowing the rocket to overcome gravity and lift off into the air.

How does launching your rocket relate to this law of motion?
If a rocket is at rest (zero momentum) in outer space, where there is no gravity, then as long as there are no Outside forces on it its momentum must always be zero (consevation of momentum). This must be true even if an internal explosion brakes it into pieces. The pieces must fly off in such a way that their net vector momentum is zero. Turning on the engine is like an internal explosion. The hot gasses, which have mass, are ejected out the back at high velocity so the gas has momentum. In order to keep the total momentum zero the rocket must move forward so its momentum just equals the backward momentum of the gasses and the net momentum of both is zero. The same is almost true when taking off from earth. Because of the Earth's gravity(outside force) the upward momentum of the rocket won't quite equal the downward momentum of the gasses but its almost the same.

In terms of impulse and momentum why is it important that helicopter blades deflect air downward?
The blades impart a downward impulse to the air and produce a downward change in the momentum of the air. The air at the same time exerts an upward impulse on the blades, providing lift. (Newton's third law applies to impulses as well as forces.)
How do action-reaction explain how a rocket lift off?
As a rocket burns fuel, it expels exhaust gases. When the gases are forced out of the rocket, they exert an equal and opposite force on the rocket. A rocket can rise into the air because the gases it expels with a downward force exert an equal but opposite force on the rocket. As long as this upward pushing force, called thrust, is greater than the downward pull of gravity, there is a net force in the upward direction. As a result, the rocket accelerates upwards.-information from Prentice Hall, Science Explorer: Physical Science

When a rocket lifts off the ground the net force is in an upward direction. Is the upward pushing force greater or less than the downward pull of gravity?
The upward pushing force is greater than the downward pull of gravity in order for the rocket to lift off the ground. This excess force allows the rocket to overcome the force of gravity and accelerate upwards.
What pushes rockets upward?
No one pushes. As the hot material comes out downward of the nozzle then the body has to move up so as to keep the total momentum zero.
What law of motion is illustrated by a rocket taking off?
The law of motion illustrated by a rocket taking off is Newton's Third Law of Motion which states that for every action, there is an equal and opposite reaction. The rocket propels itself upward by expelling gases downward, creating a reaction force that propels it forward and upward.
