Factors Affecting a Rocket's Acceleration
- The greater the exhaust velocity ve of the gases relative to the rocket, the greater the acceleration.
- The faster the rocket burns its fuel, the greater its acceleration.
- The smaller the rocket's mass (all other factors being the same), the greater the acceleration.

How do you accelerate in space?
A rocket provides the means to accelerate a spacecraft. Like an airplane's jet engine, a rocket creates thrust by expelling mass to take advantage of Sir Isaac Newton's third law (see above).
What makes a rocket go faster?
To make a rocket go faster and shorten the travel time, you want to kick material out at a higher velocity. ... Even though they use a fraction of the amount of fuel, ion engines can reach much higher speeds because of the high exhaust velocity.
Can you get acceleration in space?
The astronauts on board the International Space Station are accelerating towards the center of the Earth at 8.7 m/s², but the space station itself also accelerates at that same value of 8.7 m/s², and so there's no relative acceleration and no force that you experience. This same principle works on extreme scales, too.
Can you infinitely accelerate in space?
In the real universe, this is not possible, because the mass of the universe is finite. If you had the means to convert the mass of the entire universe into acceleration, you will exhaust the mass of the universe at some point, and you will stop accelerating. So infinite acceleration is not possible.
Does an object keep accelerating in space?
Originally Answered: Will an object, thrown in space, accelerate or travel at a constant speed? In space there is a pure (well mostly) vacuum so no such thing as air resistance. The object will continue to travel due to no other force being applied to it once it has left your, travelling at a constant speed.
Why do rockets go so fast in space?
In one second the sattilite must have a velocity that causes it to move away from the Earth by the exact distance that it falls to Earth. Typical orbital velocities around the Earth are 19 miles per second, or 67,000 miles per hour! That's why rockets travel so rapidly.
Is a rocket faster than a bullet?
Yes, this 2.8-million-kilogram rocket could outfly a rifle bullet at full speed and would travel at 7 times the speed of sound. ... With all this power, the Saturn V would reach excess speeds of 25,000 mph that is 15 times faster than a rifle bullet.
How fast does a rocket accelerate?
The ascent phase begins at liftoff and ends at insertion into a circular or elliptical orbit around the Earth. To reach the minimum altitude required to orbit the Earth, the space shuttle must accelerate from zero to 8,000 meters per second (almost 18,000 miles per hour) in eight and a half minutes.
How do you find the acceleration?
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
Is your weight 0 in space?
Astronauts on the orbiting space station are weightless because... a. there is no gravity in space and they do not weigh anything. ... space is a vacuum and there is no gravity in a vacuum.
How long would it take to safely accelerate to the speed of light?
It would take 353,7 days of constant 1G (9,81 m/s^2) acceleration to reach the speed of light. In that time you would travel 4,58 billion Km.
Do they dump poop in space?
Sometimes, astronaut poop is brought back to Earth for scientists to study, but most of the time, bathroom waste — including poop — is burned. Poop is vacuumed into garbage bags that are put into airtight containers.
What limits acceleration in space?
Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It's impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.
Can astronauts feel speed in space?
It is not possible to feel speed while in a spacecraft. Astronauts in orbit travel at 28000 km/h but feel absolutely nothing, even if they're outside.
Is there resistance in space?
There is no air resistance in space because there's no air in space. 3. GRAVITY: Gravity, which will slow down a ball thrown up in the air, is present in space.
Can you feel G's in space?
g-force is the result of acceleration of a space craft. If the ship were traveling at a constant velocity, the astronaut would experience no force at all, regardless of how fast the ship is going. Astronauts can feel g-force at any speed, so long as the ship is accelerating.
