False. Forces can also set stationary objects in motion.
True.
If the forces on an object are unbalanced then the objects motion will change. It will start accelerating in the direction of the resultant force. Only objects that have balanced forces will remain in the same motion (stationary or moving at a constant speed).
Inertia is the tendency of an object to resist a change in motion. An object would have inertia while moving and also while at rest.
It is false. Change of direction is acceleration, which can only be produced by unbalanced forces.
No, only moving things do not have energy. That is false. A light has energy, but it does not move.

Is gravity a solid? Physical collisions of solid objects is not the only way that forces can act on solid objects.
Right now I can only think of two: Wind Resistance Friction And perhaps surface tension?
Force is the only thing that causes the accelerationof material objects, whether they're moving or not.
It is false. Change of direction is acceleration, which can only be produced by unbalanced forces.

idk bghy
No...
no it is false
No, unless it is moving (e.g. you threw it, it is in a moving vehicle). Only moving objects have kinetic energy.
