Want this question answered?
the net force which is the vector sum of the forces. If that sum = 0 then no motion occurs
The density of the object or the shape of the object (like a boat) determines the buoyant force.
the force is not in the direction of the objects motion.
Inertia guarantees that an object at rest will remain at rest and an object in motion will remain in that same motion, so long as there is no external force acting on that object. Alternately, there could be force acting on it as long as that force adds up to zero.
Assuming this is a vacuum: Motion would occur only if there is no secondly force acting on the object with the same magnitude(strength) but has the opposite direction to the force you're acting upon this object.

There would have to be an unbalanced force put an object in motion but once in motion no force is necessary for it to remain in motion
the force is not in the direction of the objects motion.
Motion requires a force acting upon an object. When the object changes so does motion.
downward motion
Yes,unbalaced force may stop or change the direction of motion or accelarate the object.
No
Inertia guarantees that an object at rest will remain at rest and an object in motion will remain in that same motion, so long as there is no external force acting on that object. Alternately, there could be force acting on it as long as that force adds up to zero.
Accelerated motion (F=ma)
An object at rest or in motion with no force acting upon it.
Assuming this is a vacuum: Motion would occur only if there is no secondly force acting on the object with the same magnitude(strength) but has the opposite direction to the force you're acting upon this object.
