The force exerted only when two objects are touching is called friction. Friction occurs as a result of the resistance between the surfaces of the objects when they move against each other.
One such force is gravity; basically, gravity is the ONLY force that affects ALL objects.
No, an object cannot exert a force on itself. The concept of self-exerted force is not supported by the laws of physics. Objects can only experience forces from external sources, which can impact their motion or stability.
Yes, according to Newton's second law of motion, an object will only accelerate if a net force is applied to it. If no force is present, an object will maintain its state of motion (either at rest or moving at a constant velocity).
That force is called contact force. It is the type of force that exists between two objects only when they are in direct physical contact with each other. Examples of contact forces include friction, tension, and normal force.
They are not really lighter, they only seem lighter. Objects weigh the same in water as in air, but in the water, there is an additional force, of the water pushing the object up.

No...
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.

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.
Gravity is considered a non-contact force because it does not require direct physical contact between objects to act. It is a force of attraction between any two objects with mass, acting over a distance without the need for physical contact.
Experiences a displacement in the direction of the force.
Contact forces are they which act force when two or more bodies are in contact.It doesn't need that the body must get contact through all portion or part of the body.Just a little bit of contact is enough for this force to act.Having the contact and applying force is contact force.There is also another type of force called body force which in contrast very different. Kicking a ball is a contact force.
The force exerted by an object you are trying to move is its weight, which is equal to the mass of the object multiplied by the acceleration due to gravity (9.8 m/s^2 on Earth). The force needed to move the object must be greater than or equal to its weight to overcome friction and inertia.
