Is there more force created when 2 objects meet in motion or when 1 object is still?

Assuming all of the objects have the same mass, the answer depends on their combined velocities. If the combined vector component of velocity of two objects is the same as the velocity of the single moving object, then the force of impact will be the same. So if the two are moving in opposite directions along the same path, they will generate the same amount of force as a single object moving at a velocity that is equal to the combined velocities of the two. If the velocities are different, the force varies accordingly.

When two objects meet in motion, there is generally more force created compared to when one object is still. This is because when both objects are in motion, they have momentum which adds to the force of the collision. When one object is still, there is only the force of the moving object acting upon the still object.

When the net force on an object Is zero the object motion will?
The objects will not accelerate.
A force acting on an object does no work if?
the force is not in the direction of the objects motion.
Does a force always change an objects motion?
it usually does, but if the force is balanced, it will not change the object's motion
If the net force on an object is zero will the objects motion change?
No.
What does it take to change an objects state of motion?
it takes an unbalanced force to change an object's state of motion
How does the force of mass affect motion of object?
increasing mass affects the force of objects in motion because it will slow the object down than its neighbor
How does the force required to move an object change depending on the objects mass?
It takes no force to 'move' an object. There are trillions of objects that are moving right now with no forces acting on them. It only takes force to 'accelerate' an object ... to change its motion, by changing its speed or the direction of its motion. force=mass*acceleration As mass increases, so does the force needed to change the object's motion.
Which force resits motion between objects that are in contact?
The force that resists motion between objects that are in contact is called friction. One object can be stationary or they both can move.
What is a force that causes an object to change its motion?
I think this question is not phrased very well. Any force can change objects velocity (speed+direction). If fact that is the definition of the force - F=ma any force, by definition itself, can change objects velocity. Maybe you meant what force can change objects direction of motion? In that case - any force that has a different direction (not the same as direction of motion) Any force can change an object's motion.
What exactly changes an objects state of motion?
A net force, acting on the object.
How does force affect the motion of an object?
If you apply force to an object, you accelerate it. If you apply the force in the direction that the object is moving, you speed it up. If you apply it in the opposite direction, you slow it down. If you apply the force in another direction than the object is moving in you will change the direction of the objects motion. The amount of acceleration is given by a = F/m where a is acceleration, F is force and m is the mass of the object.
An object at rest will remain at rest and an object in straight-line motion will remain in straight-line motion unless acted upon by a?
A force, that may come from a collision with ... Another object.
