An acceleration is only possible if there is a force. In the case of a rocket, that may be gravitational forces acting on it, or it may be the reaction force of burning gases that come out of the rocket.

A rocket changes its speed in space by expelling high-speed exhaust gases through its engines. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. The rocket's engines push the exhaust gases backward, generating thrust and propelling the rocket forward, thus changing its speed.

What force pulls downwards on a rocket as it is launched into space?

Higher speeds require more space for a maneuver?
Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.
How would you turn in space if there is no gravity?
To start off, there is indeed gravity in space. Objects in orbit only seem weightless because they are already in freefall. Gravity is the main forces that affects objects in space and can be used to change a trajectory. You can also change your speed and direction in space by firing rockets.
What force keeps an object in free space going a constant speed?
No force is required to keep an object moving at constant speed in a straight line. Force is required only to change its speed or direction.
What was the fastest rocket speed?
The rocket that takes space shuttles into space recorded speeds f up to 40,000kmph. The space shuttles' rockets record up to 25,000kmph. There are also slower speed rockets.
How was the first rocket launged in space?
The first "rocket" successfully launched into space was actually a V-2 missile. The first rocket-ship that was successfully launched into space used rocket engines. A rocket engine pushes the rocket forward by expelling its exhaust in the opposite direction at a high speed.
What is the weight of a space rocket?
On earth or in space? No matter where any object is it still has the same mass (minus any fuel spent getting there). It takes quantities of energy relative to the mass to change its' speed or direction.
How do astronauts change their clothes?
They simply change there clothes! The astronauts don't always have the space suits on! That's only when they actually go into space. When there in a space station or rocket they have air tanks that replenish the air in the rocket and an air pressure controller.
The speed at which you travel in space unaided?
The speed ranges for rockets.The speed of the rocket depends on the power of the rocket. The speed may vary from 5000 kph to 40000 kph. You can only travel at 40000 kph only if the engine is at full thrust.
Why doesn't a rocket in space need to use an engine to keep moving in space?
Because there is no friction in space to slow the rocket down. Once the rocket is at its cruising speed, the engine can be switched off. Of course, that means that you have to use a different engine (pointing forwards) to slow down and stop the rocket since friction won't do it for you.
What is the speed of pslv rocket?
The speed of the PSLV-C20 rocket is 1560 km per second. PSLV stands for Polar Satellite Launch Vehicle. It was developed by the Indian Space Research Organization.
What is the speed maintained by a rocket if it is launced in outer space so it will escape the earth's gravity?
According to most sources, the minimum speed needed to escape the Earth's gravity is 11.2km/s, so a rocket would need to travel at least this fast to get into outer space.
Could you fly a rocket to Uranus?
You would need a form of extreme lubrication on the rocket to allow pleasurable passage into Uranus, as friction in space with a rocket going at that speed, without lubrication, could severely damage the rocket.
Is a space shuttle faster than a conventional rocket?
That' depends on the mission. A rocket and a space shuttle have to be in orbit and so have to fly at 8 km/s. But in certain cases, the rocket has to leave the earth (apollo, planet probe...), and then these rocket have to fly at 11 km/s. So usually the speed are the same, but sometimes, rocket are faster...
If a rocket in space burns fuel consumes energy at a constant rate its velocity should increase at a constant rate ignoring the loss of mass so why is kinetic energy a function of V SQUARED?
Assuming constant acceleration, at a higher speed, the force must be applied over a larger distance to get the same change in speed. Since work = force x distance, it requires more work to get the same change in speed, once the rocket has a higher speed.In the case of the rocket, the situation is not as simple as you put it. For example, all the fuel the rocket required to change the rocket's speed, say, from 1000 m/s to 1100 m/s, must be accelerated first, using more fuel at first. Also, the exhaust gases from the rocket have kinetic energy, which depend on the rocket's current speed - when it is just starting, the exhaust gases have a higher speed, and therefore more kinetic energy. To see whether energy is conserved or not, this kinetic energy would have to be included in your calculations.
