Objects in Motion Now consider an object in motion. straight line indefinitely. of outer space, and
the object will move forever due to inertia
.
Will an object move forever in a vacuum?
If you kick a thing in space it will not move forever
, just for a very long time. There’s always some friction and there’s always some gravitational force (or, in modern terms, all space is warped).
Can you infinitely accelerate in space?
Note that a satellite in orbit accelerate for ever towards the body it is orbiting. Well, not really for ever if you considere atmospheric drag or other types of drag, but still…
If there is no friction, stuff can accelerate forever
.
What happens if I throw a ball in space?
If one throws it in the direction of motion,
it will speed up and go further out, causing the orbital period to lengthen
. It would be at the same spot later then the station. Throwing the opposite direction will cause it to slow down, lowering it’s orbital period, and the ball will arrive first at the spot.
Can a ship stop in space?
Space ships do not stop when they run out of fuel
. While outer space does contain gas, dust, light, fields, and microscopic particles, they are in too low of a concentration to have much effect on spaceships. As a result, there is essentially zero friction in space to slow down moving objects.
Do all things move in space?
Everything in the Universe is in motion
because forces exist in the Universe. The gravitational force and the electromagnetic force ensure large objects are in motion while the weak and strong nuclear forces ensure the quantum world is constantly in motion.
Do things keep accelerating 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.
Which will fall faster in vacuum?
There is no air resistance in a vacuum. This means that under the force of gravity alone, both objects will accelerate at the same rate. Hence,
neither object falls faster
.
How long is 1 hour in space?
One hour on Earth is
0.0026 seconds
in space.
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.
Is there no drag 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.
How fast can you throw in space?
While the International Space Station orbits Earth at about
17,500 mph
, the fastest pitch on Earth, thrown by triple-A pitcher Aroldis Chapman in 2010, was clocked at a measly 105 mph. This content is imported from Twitter.
Is momentum lost in space?
Consider the rocket resting in space.
There is no momentum in the system
.
What happens if you throw a rock in space?
Yes,
it will eventually stop
, because gravity does not cease to exist in space, as derived by the formula for gravity, which employs two values, the Mass of the object and the Distance of the measurable object from another object.
What happens to fuel in space?
Inside the rocket’s engine,
fuel and oxidizers are ignited in the combustion chamber, creating hot, expanding gases
. That gas has pressure, and it pushes harder against the top of the rocket than the bottom, making it go up or forward. Since the fuel is burning, exhaust is released out the bottom.
How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that,
at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit)
.
What would happen if a spaceship ran out of fuel in outer space?
Even when the thrust that comes from the fuel runs out,
the space ship will still move forward thanks to the momentum that came from the fuel
. This momentum will then carry the space ship forward on the same trajectory that it was already travelling, even when the fuel runs out and the engine shuts off.
Why do objects fly so fast in space?
How do objects travel so fast in space? The speed of an object through space
reflects how much of its motion through time is being diverted
. The faster it moves through space, the more its motion is being diverted away from moving through time, so time slows down.
Can you travel in a straight line in space?
Objects in space follow the laws or rules of physics, just like objects on Earth do. Things in space have inertia. That is,
they travel in a straight line unless there is a force that makes them stop or change
.
Can you swim in space?
You can sort of swim, but it would be very slow
. The viscosity of air vs water is very low. Therefore the ‘scoop’ your hands or feet can get of the fluid, to propel it, and thus move you around would need to be much higher. If you had fans (or ‘wings’) on your arms you would be more effective.
Can astronauts feel speed in space?
Once at a steady cruising speed of about 16,150mph (26,000kph) in orbit,
astronauts no more feel their speed than do passengers on a commercial airplane
.
Can something accelerate forever?
If, by constant acceleration you mean “as measured in a given inertial frame”, the answer is
no, it cannot continue indefinitely
. If you mean, can a rocket accelerate such that objects inside experience constant g-force forever, the answer is yes (barring the practical constraints mentioned in Vitro’s post).
Can you feel thrust in space?
Astronauts in orbit travel at 28000 km/h but
feel absolutely nothing, even if they’re outside
. Similarly, inside a car you do not feel the speed, only the change in speed (i.e. acceleration – and note that acceleration can be in any direction: forward, backward, left, right, up or down).
What falls faster a brick or a penny?
No,
heavier objects fall as fast (or slow) as lighter objects
, if we ignore the air friction. The air friction can make a difference, but in a rather complicated way. The gravitational acceleration for all objects is the same. 3) how dense the object is.
Can gravity exist in a vacuum?
Yes, there is gravitational force in a vacuum
. Gravitational force does not depend on air.
Does gravity exist in a vacuum chamber?
Yes, gravity does exist in a vacuum
. A vacuum does not need to be completely devoid of matter, it just needs to have a lower pressure than the area around it.
