Gravitational pull and friction.
No, it is untrue. No force is required to keep a moving object moving.
gravity
It is called inertia.
"inertia"
Yes! remember Newton law of movement? An object will keep on moving forever, as long as another force or object leaves it alone. Wonderful! Your second sentence is correct, and totally contradicts your first one. The answer is: No. It is false. No force is required to keep an object moving at a constant speed in a straight line.
No, it is untrue. No force is required to keep a moving object moving.
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.
The best, purest answer is: Because no force at all is required to keep a moving object moving.
Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.
An object which is moving doesn't need a force to keep it moving.
That's true. Plus ... even if the forces on an object are BALANCED, it can keep moving forever.
to keep an object moving the way it is already moving .

It is called inertia.
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
