Why do you need rockets?

Yes, rockets need energy for launching

Because if we didn't have rockets there would be no such thing as rockets and we need them because the word "Rockets" sounds like pockets and we like words that rhyme don't we.

You need rockets so you can travel to space and visit other planets. Without rockets we would know nothing about astronomy.

Yes. Rockets have both a fuel and an oxidizing agent, so they don't need air.

birds are alive and rockets dont need air to fly birds have wings and rockets have tail fins

They need petroleum in order to burn the fuel.

you need scientist because without them how would we have rockets or any technology

Yes. For aerodynamic reasons.

Marc Halili told us that we need to fly rockets because know about space , we also have to invent something. by mark

Rockets need to carry a steady supply of oxygen so that the fire that takes them off of the ground can burn. You must remember that to have fire you must have oxygen.

To but pressure for it can fly high

Rockets need a lot of fuel because they need to fly up really high into space, and they want to make sure they have enough so the people inside don't get hurt because it runs out of fuel.

Rockets - Rockets album - was created in 1976.

Water rockets need fins because the rocket needs to stay in balance....without fins on a water rocket, the water rocket would be going out of control because it is not in balance!

the rockets the rockets the rockets

Because it needs to fit all the people

Jets and propellers need air to work, and rubber bands do not store enough energy. Rockets operate without air in the vacuum of space, and deliver enough energy to escape the surface and/or orbit of earth.

rockets need very very high speed to get on escape velocity. for this rockets liquid fuels like hydrogen (liquified) and oxygen(liquified) . the calorific value of hydrogen is very high thats why it is used

This is a bit of a silly question. Rockets create thrust which a force which keeps up. They are not dependant on air to stay u

The three kinds of rockets are solid fuel rockets, liquid fuel rockets, and ion powered rockets.

What materials do you need to build a water rocket?

the moon is small and we don't need much space

Depends on the use desired ... rockets do not need wings in general.

Rockets don't need oxygen to burn a fuel.

Water rockets use water and air modern rockets use thrust and oxygen.
