What happens when an astronaut in orbit experiences apparent weightlessness?
(B) An astronaut orbiting the Earth does feel weightless because there is no ground or normal force to counteract the force of gravity. Thus, the astronaut is falling. However, since the astronaut is also moving forward super fast, he/she continuously falls around the Earth rather than crashing into the Earth.
Are astronauts in orbit weightless explain your answer quizlet?
Are astronauts in orbit weightless? Explain your answer. No, astronauts in orbit are not truly weightless. They experience apparent weightlessness because they are in continual free fall, along with their surrounding environment.
Which explains why astronauts seem weightless in orbit?
Earth-orbiting astronauts are weightless for the same reasons that riders of a free-falling amusement park ride or a free-falling elevator are weightless. They are weightless because there is no external contact force pushing or pulling upon their body. In each case, gravity is the only force acting upon their body.
Under what condition does an object experience weightlessness?
Weightlessness is a condition when your body is in free fall and the acceleration is downward at gravity. This condition can be defined by the term zero gravity. So weightlessness occurs when there is zero support of force on our body.
What is weightlessness Class 11?
Weightlessness is a condition of free fall, in which the effect of gravity is cancelled by the inertial (e.g., centrifugal) force resulting from orbital flight. There is no force of gravity acting on the objects. It is the condition in which body does not feel its weight at all.
When in orbit astronauts experience weightlessness What is this caused by quizlet?
It an object is placed two earth-radii above the surface of the earth, then the force of gravitational attraction between the object and the earth will be one-fourth the magnitude as on earth’s surface. Orbiting astronauts do not experience a force of gravity; this explains why they feel weightless.
Why are astronauts weightless in space quizlet?
Why are astronauts weightless in the space station? because they are in a constant state of free fall around the Earth. Newton’s 1st law: An object remains in motion at constant velocity, or remains at rest, unless acted upon by a net force.
Why are astronauts in space said to be weightless but not massless?
why are the astronauts in space said to be weightless but not massless? because the force of gravity is extremely small and space in a lack of attraction between bodies that gives away to that astronauts is essentially absent. they maintain their intrinsic Mass however.
Why are astronauts weightless in the space station quizlet?
Why is it incorrect to say that astronauts are weightless in space while orbiting Earth in a space shuttle?
Why is it incorrect to say the Astronauts are weight-less in space while orbiting Earth in space in a space shuttle? A: It is correct to say they are weightless. A gravitational field doesn’t by itself make any of the effects of weight.
What is weightlessness when do objects experience weightlessness?
weightlessness, condition experienced while in free-fall, in which the effect of gravity is canceled by the inertial (e.g., centrifugal) force resulting from orbital flight.
How does an astronaut in an orbiting space station experience?
An astronaut in an orbiting space station above the earth experience weightlessness. > An astronaut in an orbiting… An astronaut in an orbiting space station above the earth experience weightlessness. An object moving around the earth under the influence of earth’s gravitational force is in a state of ‘free fall’.
What kind of force does a space station experience?
An object moving around the Earth under its gravitational force experiences centripetal acceleration due to the gravitational force. Hence an astronaut in the space station too experiences the two forces, gravitational force towards Earth, and centripetal force away from it which cancel out each other to produce weightlessness.
Why are astronauts in orbit around the Earth weightless?
Earth-orbiting astronauts are weightless for the same reasons that riders of a free-falling amusement park ride or a free-falling elevator are weightless. They are weightless because there is no external contact force pushing or pulling upon their body.
Do you feel weightlessness when orbiting the Earth?
Astronauts who are orbiting the Earth often experience sensations of weightlessness. These sensations experienced by orbiting astronauts are the same sensations experienced by anyone who has been temporarily suspended above the seat on an amusement park ride.
