Whether they are, or are not, exerted depends on the physical situation. For example, magnets won't lose their magnetic force if you make them touch. And if objects stick together, they are certainly exerting a force on one another.
Special firces
No, objects do not have to touch for a force to be involved. Forces, such as gravitational or electromagnetic forces, can act between objects even when they are not in direct contact.
No, electric force does not require objects to touch in order to act on each other. Objects with electric charge can exert attractive or repulsive forces on each other even when they are not in physical contact.
No, forces such as gravity and electromagnetic do not touch objects directly they are known as non-contact forces.
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.
Charged objects do not have to physically touch each other in order to exert a force on each other. The force between charged objects can be exerted through electromagnetic fields that extend through space. This force is known as the electrostatic force.
Magnetic and gravitational forces are non-contact forces, meaning they can act on objects from a distance without physical contact between the objects. Magnetism can attract or repel objects without direct touch, while gravity can pull objects towards each other even without touching.
Touching forces, also known as contact forces, are interactions that occur when two objects physically touch each other. They can include forces like friction, normal force, tension, and air resistance. These forces are important in understanding how objects behave and move in the physical world.
gravitational, electrostatic, and magnetic forces
The force that stops physical objects from passing through each other is the electromagnetic force. Specifically, it is the repulsion that electrons have for other electrons. When two objects touch, the electrons in the outer atomic shells are really close to each other, much closer than they are to the protons in the center of atoms which attract them, so the normally neutral atom suddenly acts as a highly negatively charged object.
A force needs to be applied in order to touch something. This force can be exerted through physical contact or interaction between two objects, causing them to make contact with one another.
