Do objects accelerate only when a force is exerted upon it?
yes
What is the name of the natural pulling force exerted by objects on one another?
One such force is gravity; basically, gravity is the ONLY force that affects ALL objects.
When a force is exerted on an object work is done only if the object?
Only if the object moves
Why is gravity considered a non contact force?
Non-Contact ForcesWhile the ball is in the air, one force acting on it is gravity. Gravity pulls the ball down to the earth without touching it. This means it is an example of a non-contact force, or a force exerted on an object that does not make contact with it. Another example of a non-contact force is magnetism. Read more about magnetism.
Which term is a pulling force exerted by solids?
Tension is a pulling force that is exerted by solids.

What is the force exerted by the object you are trying to move?
Its a reaction force, and is equal and opposite to your force, only it is acting on different objects, so the force is still unbalanced.
Are forces only exerted when objects touch each other?
No...
What is a force only exerted when objects touch?
A contact force? The answer really depends on the level of the question. Primary school answer: A pushing or pulling force, or a friction force occur when objects touch. High school answer: Same as above, but 'pushing' and 'pulling' would be replaced with positive and negative. Friction would be defined as a force that opposes motion, and would include air resistance and drag. University answer: Technically, there is no such force, as all forces act at a distance without touching. In fact, objects don't actually 'touch' one another at all. The outer electrons in an object's atoms will repel said electrons from another object's atoms through the electromagnetic force. This only makes it feel like the objects have come into contact with one another, when in fact they haven't.
Is the mutual gravitational force exerted by a pair of objects affected by the nature of the inverting medium?
Inverting? I assume you mean the surrounding medium, or the medium in between. No; the gravitational force depends ONLY on the masses, and on the distance. Of course, anything between the two objects may exert forces OTHER than the gravitational force.
When a force is exerted on an object work is done only if the object?
Only if the object moves
Why is the work output less when a force is exerted at an angle than when the force is exerted parallel to the direction of motion?
Because only a part of force (see vector analysis) is being used to do the desired work.

Do action and reaction forces cancel each other?
Yes and no. They are equal in size and opposite in direction, but they are NOT exerted onto the same object. Each object exerts exactly one force and each object RECEIVES exactly one force. With only one force being exerted onto each object, there is nothing to be cancelled on each single object. Thus, they do not cancel, they simply exert themselves on different objects.
Which term is a pulling force exerted by solids?
Tension is a pulling force that is exerted by solids.
If two objects have an equal mass does a more dense object have a greater gravitational pull?
No. The gravitational force exerted by one massive object on others depends only on its mass. So long as you are outside of the object, its density is irrelevant.
