What force is acted on by another?
Forces don't act on other forces - forces act on objects.
What forces act on still objects?
The would be balanced forces.
When no outside forces act on asystem of objects what do the objects do?
If there are no outside forces acting on a system of particles the total momentum of the system will remain constant; i.e. the center of mass of the system will remain at rest or move at constant velocity.
Why do all forces have to act on objects?
gravity
What forces act on falling objects?
gravity and drag
1 In what direction do the gravitational forces act?
Gravitational forces are attractive only. They act on a line from the center of mass of one object, to the center of mass of another object, and work to bring the two objects closer together.

Action-reaction forces always act on what kind of objects?
Action-Reaction forces act on all matter.
Can only solid objects exert forces?
Is gravity a solid? Physical collisions of solid objects is not the only way that forces can act on solid objects.
Why does and object move if the action reaction forces are equal?
Action and reaction forces act on different objects. The forces on one of the objects can still be unbalanced.
Is a body in motion stays in motion?
That depends. If no forces act on the object, it will. If forces do act on the objects, such forces may change the object's velocity.
Does gravity act only on objects with mass?
Yes. But that has not proven to be a serious limitation. How many objects can you name that have no mass ?
The total momentum of a group of objects is conserved unless?
b. outside forces act on the objects.
