Best Answer

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.

Why does a rocket need to fight gravity?

In general, it doesn't. That's only necessary if the rocket wants to get off of the ground.


What would happen if the thrust of the rocket at take off was not enough to put the rocket in orbit around the earth?

It would crash like NASA's Titan rocket did.

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.

Why does rocket taking off from the earth needs much more fuel than the same rocket taking off from the moon?

dunno and it need answer gravity is very strong on earth as the rocket gets higher gravity gets weaker they have to overpower gravity to lift of
