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 accelerate forever in space?
yes. you can accelerate forever
. your rate of increase in absolute speed will simply dimish as you get closer and closer but never actually reaching the speed of light.
Can rocket ships accelerate in space?
In space,
rockets zoom around with no air
to push against. … Rockets and engines in space behave according to Isaac Newton’s third law of motion: Every action produces an equal and opposite reaction. When a rocket shoots fuel out one end, this propels the rocket forward — no air is required.
How fast can we accelerate a spaceship?
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.
How long is 1 hour in space?
How is 1 hour in space equal to
7 years
on Earth.
Whats the fastest we can travel in space?
But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than
300,000 kilometers per second (186,000 miles per second)
.
How fast is 1g in space?
At a constant acceleration of 1 g, a rocket could travel the diameter of our galaxy
in about 12 years ship time
, and about 113,000 years planetary time. If the last half of the trip involves deceleration at 1 g, the trip would take about 24 years.
How fast is 1 g in mph?
An acceleration of 1 G is equivalent to a speed of
about 22 mph
(35 km/h) per second.
Are there Gs in space?
Even though the force of gravity is really there, accelerating the ship and everything inside, this is not a perceptible sensation.
The force of gravity is always present
, no matter where you are in the Universe.
What does space smell like?
In a video shared by Eau de Space, NASA astronaut Tony Antonelli says space smells
“strong and unique
,” unlike anything he has ever smelled on Earth. According to Eau de Space, others have described the smell as “seared steak, raspberries, and rum,” smokey and bitter.
Is it true that 1 hour in space is 7 years on Earth?
Answer: The time-dilation effect of Einstein’s relativity
has nothing to do with space
. The faster you’re moving, the slower time goes for you. So if you were on some planet moving extremely fast through space, like in the movie Interstellar, then you could miss 7 years on Earth every hour.
Has anyone ever floated away in space?
The STS-41B was launched on February 3, 1984. Four days later, on February 7,
McCandless
stepped out of the space shuttle Challenger into nothingness. As he moved away from the spacecraft, he floated freely without any earthly anchor.
Can humans travel light speed?
We can never reach the speed of light
. Or, more accurately, we can never reach the speed of light in a vacuum. That is, the ultimate cosmic speed limit, of 299,792,458 m/s is unattainable for massive particles, and simultaneously is the speed that all massless particles must travel at.
How fast can Rockets travel in space?
If a rocket is launched from the surface of the Earth, it needs to reach a speed of
at least 7.9 kilometers per second
(4.9 miles per second) in order to reach space. This speed of 7.9 kilometers per second is known as the orbital velocity, it corresponds to more than 20 times the speed of sound.
Will we ever travel faster than light?
General Relativity states that space and time are fused and
that nothing can travel faster than the speed of light
. General relativity also describes how mass and energy warp spacetime – hefty objects like stars and black holes curve spacetime around them.
How fast is 7 g force?
100kph is
28m/s
, 28 / 2.3 = 12m/s2, 12 / 9.8 = 1.2g.
