What exactly is a "non-contact force"?- this must be the question.
A non-contact force is a force applied to an object by another body that is not in direct contact with it. The most familiar example of a non-contact force is gravity. In contrast a contact forceis a force applied to a body by another body that is in contact with it. However it is to be noted that the origin of all contact forces (such as, for example, friction) can be traced to non-contact forces.
All four known fundamental interactions are non-contact forces:
- Gravity, the force of attraction that exists among all bodies that have mass. The force exerted on each body by the other through weight is proportional to the mass of the first body times the mass of the second body divided by the square of the distance between them.
- Electromagnetismis the force that causes the interaction between electrically charged particles; the areas in which this happens are called electromagnetic fields. Examples of this force include: electricity, magnetism, radio waves, microwaves, infrared, visible light, X-rays and gamma rays. Electromagnetism mediates all chemical, biological, electrical and electronic processes
- Strong nuclear force: Unlike Gravity and electromagnetism, the strong nuclear force is a short distance force that takes place between fundamental particles within a nucleus. It is chargeindependent and acts equally between a proton and a proton, a neutron and a neutron, and a proton and a neutron. The strong nuclear force is the strongest force in nature; however, its range is small (acting only over distances of the order of 10−15 m). The strong nuclear force mediates both nuclear fission and fusionreactions.
- Weak nuclear force: The weak nuclear force mediates the β decay of a proton, in which the protondecays into a neutronand in the process emits a β particle and an uncharged particle called a neutrino. As a result of mediating the β decayprocess, the Weak nuclear force plays a key role in Supernova. Both the strong and weak forces form an important part of quantum mechanics. (Wikipedia)

What three forces?
three forces are gravitational,,electromagnetic,and weak nuclear
What are the differences between plane forces and space forces?
In plane forces, all forces are confined to a two-dimensional plane, while in space forces, forces can act in three dimensions. Plane forces involve only forces in the x and y axes, while space forces can include forces in the z axis as well. Space forces require vector analysis in three dimensions, while plane forces use scalar analysis in two dimensions.
What are the three forces of erosion?
The three main forces of erosion are wind, water, and ice, with an assist from gravity.
What are the three forces that act on an object?
The three forces that act on an object are gravity, friction, and applied force.
What are the three g forces?
The three types of g-forces are positive g, negative g and lateral g.
What three forces are considered to be the fundamental forces of nature?
The three fundamental forces of nature are the strong nuclear force, the weak nuclear force, and the electromagnetic force. These forces govern the interactions between particles at the atomic and subatomic levels.
What is the direction of resultant of three like parallel forces?
The direction of the resultant of three like parallel forces will be the same as the direction of the original forces. If the forces are all acting in the same direction, the resultant will also act in that direction.
Three opposing forces in the Russian government?
The three opposing forces in the Russian government were the conservatives, the social democrats, and Lenin's followers.
If three concurrent forces are in equilibrium what is the relation between any one of the three forces and the resultant of the other two forces?
If three concurrent forces are in equilibrium, then each force is proportional to the resultant of the other two forces. This means that the magnitude and direction of each force are determined by the other two forces, ensuring that the system remains in equilibrium.
What are the three different places on a bridge that would experience different forces?
The three different places on a bridge that would experience different forces are the supports (where vertical forces are highest), the center span (where compression and tension forces are highest), and the connections between bridge sections (where shear forces are highest).
What three things can forces change?
Forces can change the speed, direction, and shape of an object.
What forces are present in a three charge system?
In a three-charge system, the forces present are the electrostatic forces of attraction or repulsion between the charges. These forces are determined by the magnitudes and signs of the charges, as well as the distances between them, according to Coulomb's Law.
