They measure the velocity of the object after applying a accurately measured force.
Microgravity Confinement
Calculations, reasoning... math can do a lot.
generally, grams. Grams is also the unit of measurement for the majority of the world.
Scientists discover things about space through observations made using telescopes and satellites, as well as through experiments conducted in space missions. They also analyze data collected from these observations and experiments to better understand the phenomena in space. Collaboration between different scientific disciplines, such as astronomy, physics, and astrophysics, also plays a crucial role in discovering new things about space.
Is your question "what do you weigh different objects on in space...", or "why would you attempt to weigh an object in space"...?
As of now, there is no confirmed evidence of living things in outer space aside from Earth. Scientists continue to explore space for signs of extraterrestrial life, such as microbial organisms on other planets or moons.
Scientists do research, do test and go into a space vehicle to do experiments. They also go out the space vehicle in space suits.
scientists use spacecraft without people to explore space because scientists need to know more about space and the solar system
Scientists find things out by doing experiments.
Scientists use light years to calculate distance because they can tell how far away things are in space by measuring how much time it takes for light to reach a certain point. It's just easier to say how many light years things are in space then to say in miles.
Scientists at NASA do various things. The tasks are all space or physics related. NASA is US's Space Program. They launched satellites like Swift,skylab ect. NASA scientists test zero G, jet propulsion, sample space rocks ect. Space Shuttles and Mars Rovers are one of NASA's achievements.
Scientists refer to the study of things related to space as "astronomy." This field encompasses the observation and analysis of celestial objects, such as stars, planets, and galaxies, as well as phenomena beyond Earth's atmosphere. Astronomy combines aspects of physics, chemistry, and mathematics to understand the universe's structure, origins, and evolution.
