How come an asteroid have gravity but the space shuttle does not?
Technically all objects have gravity, however, an object's gravity depends on its mass. In order for its gravity to be noticeable an object must have a very large mass. The space shuttle weighs a couple thousand tons, which is not enough for there to be noticeable gravity. Many asteroids have masses of millions to trillions of tons.
Can asteroids turn into black holes?
No. An asteroid does not have enough mass. In order to become a black hole an object must be massive enough to be crushed by its won gravity. This takes an object at least several times more massive than the sun.
What does an object need in order to have gravity?
There is a force of gravity between every pair of masses. So any object with mass is attracted to every other object with mass.
What best describes what must happen in order for a person to lift an object?
The force of gravity must be greater than the mass of the object
How is orbit and gravity related?
When it an object in space in moving it will keep moving at the same speed with the property of inertia. Then moon is an object that has inertia. Gravity keeps the moon from going off into outer space but inertia keeps the moon from crashing into the moon. Gravity and inertia have to be balanced in order for an object to remain in orbit.
What would have to happen to the two factors that determine an object's gravity force in order for the object to exert more gravity force?
Two possibilities: -- It's mass increases. -- It comes closer to the object it's attracting. Either of those changes increases the gravitational forces between them.
What must a rocket overcome in order to reach orbit?
If you want something to orbit the earth, then you have to throw it at superhuman speed. Actually, on roller coasters, you sometimes feel like you are floating out of your seat. If it wasn't for your seatbelt, you could've orbited the earth!
Which statements best describes what must happen in order for a person to lift an object?
The force of gravity must be greater than the mass of the object
What is push or pull that makes an object move or puts it into motion?
A push or pull that acts on an object is a force.
How fast does something need to be to escape the gravity of a black hole?
In order to escape the gravity of a black hole, an object would have to travel faster than the speed of light - something that is impossible.
Why gravitational force is considered as non-contact force?
The Earth does not need to touch you in order to attract you to it. If you do nothing but simply let go of the airplane you're riding in, that's quite enough. Gravity can do its job and easily bring you to the Earth, without any contact. Quite unlike fly-paper.
Is it possible for a person to be so fat that said person has a gravitational pull?
Everything that has mass exerts a gravitational pull on everything else with mass... but gravity is such a weak force that objects need to be huge in order to have any noticable effect. No person will ever be big enough that they can noticably attract objects around them.
