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.

What else can I help you with?
What is a example of a rocket fires engines and lifts off?
the rocket is accelerating
How do action reaction pairs explain how a rocket lifts off?
Rocket emits particles backward with great force. This means that there is also a force in the other direction, which pushes the rocket forward. Also apparent from conservation of momentum.
A rocket lifts off by pushing down on the ground which then pushes the rocket up?
The propellant
What is the name of the background song in the Toyota lift off commercial where some guy lifts off in a rocket?
The name of the background song in the Toyota lift off commercial where some guy lifts off in a rocket is Lift Off. This is a song which is done by Jay-Z and Kanye West.Ê
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
Can the smoke from a model rocket kill you?
Probably not, but I wouldn't recommend standing too close to the rocket as it lifts off. The fumes from the rocket's engine definitely aren't very good for your lungs.
When a rocket lifts off its upward momentum is matched by the downward momentum of?
the expelled gases. As the rocket pushes off the gases at high speed, the equal and opposite reaction pushes the rocket in the opposite direction with an equal force, propelling it upwards.
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.
What are the things that decrease as a rocket lifts off the ground?
The first thing that decreases when the rocket takes off the ground is the hybrid fuel in the large tanks attached with it. As it takes off and approaches to the outer atmospheric line the tanks attached are detached and then the boosters come off from the rockets. Thus it decreases the number of accessory parts after the take off.
How does a rocket launch off the ground?
A rocket launches off the ground by expelling propellant at high speed from its engines, which generates thrust according to Newton's third law of motion: for every action, there is an equal and opposite reaction. As the engines burn fuel, the combustion gases are forced out of the rocket's nozzles, pushing the rocket upward. The thrust must overcome the force of gravity and atmospheric drag for the rocket to ascend. Once sufficient thrust is achieved, the rocket lifts off and begins its journey into space.
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 makes a rocket fly?
A rocket flies by using the principle of Newton's third law of motion, which states that every action has an equal and opposite reaction. The rocket engine expels high-velocity exhaust gases in one direction, creating a force that propels the rocket in the opposite direction. This results in thrust that lifts the rocket off the ground and into the air.
