Why does a rocket need a large thrust on take off from the earth?
A rocket needs a large thrust on takeoff from Earth to overcome the force of gravity pulling it down. The large thrust is necessary to generate enough speed to reach escape velocity and break free from Earth's gravitational pull. Once the rocket is in space, it needs less thrust to maintain its course.
What does a rocket need to take off?
A rocket needs a powerful thrust to overcome Earth's gravity and lift off. This thrust is typically provided by rocket engines that burn fuel to create a force that propels the rocket upward. Additionally, the rocket needs a stable structure to withstand the forces of liftoff and the harsh conditions of space.
What you do to send a rocket into space?
To send a rocket into space, you need to first assemble the rocket, fuel it, and then launch it into the atmosphere. The rocket needs to achieve enough velocity and altitude to escape Earth's gravitational pull and enter space. This involves careful planning, engineering, and coordination of various systems to ensure a successful launch.
How much force does it take to break away from earths gravity?
To break away from Earth's gravity and reach space, an object needs to reach an escape velocity of about 11.2 kilometers per second (about 25,000 mph). The force required to achieve this velocity is enormous and depends on the mass of the object. For example, a spacecraft with humans onboard would need powerful rockets to generate enough force to break free from Earth's gravity.
Why must a spacecraft reach escape velocity to be able to go to space?
Escape velocity is the minimum speed required for an object to break free from the gravitational pull of a planet or celestial body without any further propulsion. In the case of spacecraft, reaching escape velocity allows it to overcome Earth's gravitational pull and venture into space without being pulled back down. It is necessary to ensure that the spacecraft can achieve its intended trajectory and continue its journey into space.
What force does a rocket have to overcome to move skyward?
A rocket has to overcome the force of gravity in order to move skyward. This force pulls the rocket downward and needs to be overcome by the thrust generated by the rocket's engines in order to achieve lift-off.
How many newtons of force does a rocket need to take off?
This depends on the weight of the rocket, weight being the mass of the rocket multiplied by earth's gravitational pull. To take off, the rocket needs to exert force larger than the weight, and for a sufficient amount of time to break out of orbit. For instance, if the rocket had a mass of 1kg, it'd exert (1 * 9.8), or 9.8 Newtons of force towards to ground via it's weight (9.8 being the acceleration towards the ground due to gravity). This means that to start to accelerate away from the ground, the rocket would need to exert force higher than 9.8 Newtons. If your hypothetical rocket has a mass of x kg, then it will need to exert a force greater than 9.8x newtons, ignoring air resistance and decaying of the gravitational field.

How big is the upward force compared to the downward force?
Down ward force is greater than upward force because everything on earth, obeys the laws of gravity, and for a rocket to take off from earth it needs more energy in other to fight the earths gravitational force but despite fighting the gravitational force it still doesnt take off with a full speed, But for a body of mass to fall from the atmosphere its falls with a great speed due to the force of the earths gravity.
Is propulsion a force?
Propulsion is the force that moves an object forward. It is the result of applying force to the object in the opposite direction it needs to move. For example, in a rocket, propulsion is generated by expelling propellant gases backwards, causing the rocket to move forward.

Additionally, the rocket needs a stable structure to withstand the forces of liftoff and the harsh conditions of space.
Why does more weight needs more force?
More weight requires more force to overcome the force of gravity acting on the object. The force of gravity is directly proportional to an object's mass, meaning heavier objects experience a greater gravitational force pulling them downward. To lift or move heavier objects, more force must be applied to counteract this gravitational force.

Why does the rocket have to go sideways?
The rocket needs to go sideways to reach orbit. By moving sideways fast enough, the rocket can overcome the force of gravity pulling it back towards Earth. This sideways velocity allows the rocket to enter a stable orbit around Earth.
How much force does it take to break away from earths gravity?
To break away from Earth's gravity and reach space, an object needs to reach an escape velocity of about 11.2 kilometers per second (about 25,000 mph). The force required to achieve this velocity is enormous and depends on the mass of the object. For example, a spacecraft with humans onboard would need powerful rockets to generate enough force to break free from Earth's gravity.
Why gravitational potential is negative?
Gravitational potential is considered negative because work needs to be done to move an object from an infinite distance to a certain point in the gravitational field. As the object moves closer to a massive body, the potential energy decreases, resulting in a negative value to reflect the work done against the gravitational force.
Why must a spacecraft reach escape velocity to be able to go to space?
Escape velocity is the minimum speed required for an object to break free from the gravitational pull of a planet or celestial body without any further propulsion. In the case of spacecraft, reaching escape velocity allows it to overcome Earth's gravitational pull and venture into space without being pulled back down. It is necessary to ensure that the spacecraft can achieve its intended trajectory and continue its journey into space.
