Is gravitational force equal to weight?
The gravitational force on Earth is equal to the force the Earth exerts on you. At rest, on or near the surface of the Earth, the gravitational force equals your weight.
What two factors does gravitational force depend on?
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
Does gravitational force depend on speed?
There is a clear relationship between the gravitational force on a planet and its orbital speed. That relationship depends on the mass of the Sun. This is misleading because this is EXACTLY what everyone wants to say – that a greater force on an object makes it go faster.
What two factors will make an object stable?
The stability of an object is dependent on two factors:
- The base width of the object.
- The center of gravity.
Is gravity stronger at night?
Gravity is weaker in the dark areas you see in the field of the deep of spacetime during the night.
How do you make a stronger gravitational pull?
Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.
Why is gravity so strong in a black hole?
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can’t see black holes.
Can u get pregnant in space?
While no astronauts have admitted having sex in space, plenty of reproduction has been going on. This is because a range of animals from fruit flies to fish – as well as their eggs, sperm and embryos – have been sent into space so we can study how they reproduce.
Who was the first person to poop on the moon?
astronaut Charlie Duke
How do female astronauts pee?
Astronauts pee directly into the hose, which suctions the pee straight to the UPA. To go #2, however, they have to use something that looks a little more like a toilet.
Are there any human bodies in space?
Humans have sustained direct presence in orbit around Earth since the year 2000 through continuously crewing the ISS, and with few interruptions through crewing the space station Mir since the later 1980s.
What foods aren’t allowed in space?
Here are five foods that NASA Astronauts can’t eat in space:
- Bread. U.S. Food and Drug Administration.
- Alcohol. United States Embassy, Berlin.
- Salt and Pepper. Getty Images / iStock.
- Soda. Getty Images / iStock.
- Astronaut Ice Cream.
Do astronauts drink pee?
Astronauts have been drinking distilled urine since 2009, and they currently recapture 93 percent of wastewater, but the system they’re using now is heavy, slow and has been prone to breaking down. It spins the urine at high speed to separate out the water vapor, then treats it chemically.
