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 force can change the direction of the rocket's motion but not its speed if the force is applied perpendicular to the rocket's velocity. If the force is applied in the same direction as the rocket's motion, it can accelerate or decelerate the rocket.
No, a rocket does not stay at the same speed throughout its journey. The rocket experiences acceleration as it moves through the atmosphere and then into space. During this acceleration phase, the rocket speeds up until it reaches its desired velocity for the remainder of its journey.
If the moving gases of a rocket have a greater mass and speed, the rocket will experience increased thrust, resulting in higher acceleration and velocity. This leads to improved performance and efficiency in terms of reaching its intended destination in space.
Rockets work based on the principle of conservation of momentum. By expelling high-speed exhaust gases in one direction, a rocket generates an equal and opposite force that propels it in the opposite direction. This action results in a net change in momentum and allows the rocket to move forward in the vacuum of space.
The rocket speed increases every second because of the continuous burning of fuel, which generates thrust that propels the rocket forward. As the fuel is burned and expelled as exhaust, the rocket becomes lighter, allowing it to accelerate due to the conservation of momentum. Additionally, there is minimal air resistance in space, enabling the rocket to accelerate more efficiently.
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.
A rocket's speed at launch is typically zero, as it starts from a stationary position on the ground. The rocket gradually accelerates as it is propelled by its engines, reaching higher speeds as it ascends into space.
A force can change the direction of the rocket's motion but not its speed if the force is applied perpendicular to the rocket's velocity. If the force is applied in the same direction as the rocket's motion, it can accelerate or decelerate the rocket.
It takes around 8 minutes for a rocket to reach space and escape Earth's atmosphere. This can vary slightly depending on the specific rocket and its speed.
It has several engines for maneuvering, which are located on its sides and even on the front part. Short impulse from these engines allow a rocket to change its moving direction, you can check out Youtube videos with Space Shuttle maneuvering to see it yourself.
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.
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.
No, a rocket does not stay at the same speed throughout its journey. The rocket experiences acceleration as it moves through the atmosphere and then into space. During this acceleration phase, the rocket speeds up until it reaches its desired velocity for the remainder of its journey.
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.
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.
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.
