The thrust of a rocket on liftoff can vary depending on the rocket's design and size. For example, the Falcon 9 rocket produces about 1.7 million pounds of thrust at liftoff.
During liftoff, the two main forces acting on a rocket are thrust and gravity. Thrust is generated by the rocket's engines, pushing it upward, while gravity pulls the rocket back towards the Earth. These forces must be balanced for the rocket to achieve liftoff and ascend into space.

The amount of fuel a rocket burns during liftoff depends on the specific rocket and mission. On average, a rocket like the Falcon 9 may burn around 400,000 to 700,000 gallons of fuel during liftoff. The Saturn V rocket used for the Apollo missions burned approximately 20 tons of fuel per minute during liftoff.
During the liftoff of a rocket, the two main forces present are thrust and gravity. Thrust is the force generated by the rocket engines pushing against the ground, propelling the rocket upwards, while gravity acts in the opposite direction, pulling the rocket downwards.

The main forces that act against a rocket are air resistance (drag) and gravity. Air resistance causes drag as the rocket moves through the atmosphere, which can slow it down. Gravity pulls the rocket back towards the Earth, requiring the rocket's engines to generate enough thrust to overcome it and achieve liftoff.
The structure that supports a rocket before launch is called a launch pad. It provides a stable platform for the rocket to stand on and facilitates the safe ignition and liftoff of the rocket.
The Space Shuttle used approximately 1.6 million pounds (800 tons) of solid rocket fuel during liftoff. This solid rocket fuel was primarily used in the twin solid rocket boosters that provided the initial thrust to launch the shuttle into space.
The stages of a rocket taking off include ignition, liftoff, ascent, staging, and orbital insertion. During ignition, the rocket's engines are started. Liftoff is when the rocket begins to ascend into the sky. Ascent is the phase where the rocket climbs higher into the atmosphere. Staging involves separating the rocket's sections or stages once their fuel is depleted. Finally, orbital insertion marks when the rocket reaches its intended orbit.
