Contact forces, such as friction, normal force, tension, and applied force, only have an effect on objects they touch. These forces require physical contact between objects to manifest and influence the motion or deformation of the objects involved.
Forces can act on an object without touching it through fields. In the case of gravitational forces, objects are attracted to each other through gravitational fields, without physical contact. Similarly, magnetic or electric fields can exert forces on objects without direct contact.
Forces can't be felt directly because they only produce motion or deformation in objects. The sensation of feeling is related to interactions involving touch and pressure, which are caused by physical contact between objects. Forces, such as gravity or electromagnetic forces, do not involve direct physical contact with our sensory receptors, so we do not directly feel them.
False. Forces can also set stationary objects in motion.
Contact force. This force only acts upon objects that are in direct physical contact with each other. Examples include friction, tension, and normal force.
Electric forces are typically only noticeable when dealing with objects that have a strong charge imbalance, such as in the case of static electricity or lightning. In everyday situations, most objects have neutral charges overall, which makes the electric forces between them too weak to be perceptible to our senses.
No...
Is gravity a solid? Physical collisions of solid objects is not the only way that forces can act on solid objects.
I don't think so. The earth doesn't have to touch a rock in order for the force of gravity to pull the rock towards the earth. A magnet doesn't have to touch a paper clip in order to pick it up off the table and pull it all the way to the magnet.

color only affects the cooling time of objects if there is light
Contact forces are forces that can only have an effect on objects that they touch, such as when you contact a box and apply force to move it. you might apply a contact force to bend, tear, stretch, compress, or twist and abject. Tension force, friction force, and elastic force are examples of contact forces.

Because of Newton's First Law of Motion.

In everyday situations, most objects have neutral charges overall, which makes the electric forces between them too weak to be perceptible to our senses.
A contact force, such as friction. If a car wheel wasn't on the ground there couldn't be friction. A non-contact force could be magnets, the two magnets don't need to touch to repel or attract :)
