Our daily experience on earth teaches us that objects in motion tend to stop.
We learn this as babies, and it's one of our instincts for life. But it's wrong.
The way nature actually works is: An object in motion keeps going, in a straight line
with constant speed, until an external force makes it change speed or direction.
We've known this for roughly 500 years, since Galileo reasoned it out, explained it,
and proved it.
The earth keeps moving because there's no external force to make it stop.

What forces keep the Earth moving?
No force makes the Earth move. It has enough momentum to continue moving through space.
What does the water keep moving on the surface and into the earth mean?
Being in the liquid form water keeps on moving on the surface and into the earth due to gravitation force of the Earth.
Is it true that to keep an object moving a force must be apllied?
No, it is untrue. No force is required to keep a moving object moving.
How do planets in the solar system keep moving?
An object has a general tendency to keep moving - that's how our Universe works. No force is required to keep an object moving - unless there is another force that slows it down. Here on Earth, there are usually frictional forces that slow objects down, and therefore a force is required to counteract the frictional forces.
Does it take the same amount of force to start something as it does to keep it moving?
No. It takes a force to put something in motion, and it takes force to stop it. To keep it moving requires zero force. If there is no opposing friction force, it will continue moving forever. If you can significantly reduce the friction, a small force can keep an object moving - just enough to counteract the force of friction.No. It takes a force to put something in motion, and it takes force to stop it.

Is force always neede to keep an object moving?
Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.
What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
Why do you have to exert extra force to get a heavy object moving and then have to keep applying force to keep it moving at constant velocity?
the heavier and the bigger the object the more force you need to use to keep it moving . the less weight and the smaller an object is the less force you need to use to keep it moving. it always depends on the weight of the object and the size of the object.
What force keeps a space probe moving?
No force is required to keep something moving. According to Newton's Second Law, you need a force to speed something up, or to slow something down - not to keep it moving.
No force is necessary to?
to keep an object moving the way it is already moving .
What is the force that keep an object moving?
gravity
Why is less force neede needed to keep an object moving than to start the object in motion.?
The best, purest answer is: Because no force at all is required to keep a moving object moving.
