How do you measure the weight of a satellite?
You can use either F=ma or F= GmM/r^2. “a” is just the acceleration due to the gravitational force at the earth’s surface. Thus “a” is GM/r^2 where G is the gravitiational constant, M is the mass of the earth, and r is the distance between the center of mass of the earth and the center of mass of the satellite.
How do astronauts weigh things in space?
In place of a scale, NASA astronauts use something called a Space Linear Acceleration Mass Measurement Device (SLAMMD) to “weigh” themselves. Once they mount the pogo stick-like contraption it moves them a meter using a built-in spring. Measuring weight isn’t the only everyday activity that’s complicated in space.
What will be your weight when orbiting in a space satellite?
Astronauts on the orbiting space station are weightless because… a. there is no gravity in space and they do not weigh anything.
How do you calculate the weight of an astronaut on Earth?
As we know the gravitational force acts on any body near the planet that force is called weight, the value of the weight is given by: W=m gp W = m g p where m is the mass of the body and gp is the acceleration due to gravity on any planet.
What is the weight of satellite?
The size of a satellite can be anything from few centimeters to as big as football field and their weight can be as low as few grams to 10s of tons. It is currently the world’s lightest satellite weighing a mere 64 grams. It weights around 450 tons and costs more than $150 Billions to construct.
How do we measure the distance between satellites and Earth?
F=GMmr2 . Where G=6.67384m3kg⋅s2 is the gravitational constant, M=5.972⋅1024kg is the mass of the Earth, m is the mass of the satellite and r is the distance from the centre if the Earth to the satellite. F=m⋅r⋅ω2 .
How do astronauts measure distance in space?
Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. He described parallax as the “gold standard” for measuring stellar distances because it does not involve physics; rather, it relies solely on geometry. …
What is the weight of an astronaut in an artificial satellite revolving around the Earth?
Assertion(A): The apparent weight of an astronaut in artificial satellite of earth is zero. Reason(R) : The centrifugal force on the astronaut is equal and opposite to earth gravitational force on him.
Are astronauts really weightless in space?
The astronauts, the ISS itself and other objects in Earth orbit aren’t floating, they are actually falling. So, as they accelerate towards the Earth, the Earth curves away beneath them and they never get any closer. Since the astronauts have the same acceleration as the space station, they feel weightless.
Why Astronauts weigh less on the moon?
Density is a measure of how much mass is concentrated in a given space. Sir Isaac Newton discovered that as an object’s mass increases, the gravitational attraction of that object increases. Thus, the gravitational attraction on the Moon is much less than it is here on Earth, and a person weighs less on the Moon.
How heavy is a spaceship?
A spaceship is typically larger than a spacecraft, typically above 40 tons in weight. A Light Spaceship weighs between 40 and 100 tons and requires ten to thirty crewman. A Medium Spaceship weighs between 100 and 1000 tons and requires twenty to five-hundred crewmen.
Why can’t we measure the weight of astronauts in space?
The first obstacle is that in the microgravity of space, their weight is essentially zero, all the time. But astronauts still have mass, which they can measure to determine what their weight on Earth would be, and to let medical researchers track changes in body mass due to deconditioning in orbit.
How is weight calculated on the International Space Station?
Currently, crews on board the space station use two devices to calculate their weight. The first is NASA’s Space Linear Acceleration Mass Measurement Device (SLAMMD), which relies on Newton’s Second Law of Motion.
How do they measure mass in space?
The other device is Russia’s Body Mass Measurement Device (BMMD), seen being demonstrated by Reid Wiseman in this Vine he posted last October. The astronaut rides the BMMD somewhat like a pogo stick, and the oscillation of a spring is used to measure mass.
How do astronauts measure the mass of a spring?
The ISS astronauts use this property of springs for measuring their mass. According to Newton’s second law, force is equal to mass times acceleration. If a spring always produces a known force, all the astronauts have to do is push themselves with a spring and measure how much they accelerate.
