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 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.

A rocket lifts off by pushing down on the ground which then pushes the rocket up?
The propellant
How is the mass of the rocket change when it lits of?
The mass of the rocket decreases when it lifts off due to the expulsion of propellant (fuel) through the engines as exhaust gases. This process generates thrust, propelling the rocket upward while reducing its overall mass as fuel is consumed.
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.
How long does a rocket take to take off?
From the time the Space Shuttle's on-board computers start the launch sequence until the time the shuttle actually lifts off the pad is about 31 seconds. About 60 seconds after lift off, the engines on the shuttle are at maximum throttle.
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
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.
What are the stages got a rocket launch?
A rocket launch typically involves several key stages: Preparation: This includes assembly, testing, and fueling of the rocket, along with final checks to ensure all systems are operational. Launch: The rocket ignites its engines and lifts off from the launch pad, overcoming Earth's gravity. Ascent: The rocket travels through the atmosphere, with stages that may separate to reduce weight and increase efficiency. Orbit Insertion or Mission Phase: Once in space, the rocket completes its mission, whether that’s entering orbit, deploying payloads, or traveling to another destination.
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.
