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.
The four known fundamental interactions are all 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.

What is the definition of non-contact forces?
A non-contact force is any force applied to an object by another body that is not in direct contact with it. Ex. Gravity, Magnetism
What do contact and non-contact forces have in common?
they both are forces
Which forces are non-contact forces?
Non-contact forces include gravitational force, electromagnetic force, and nuclear force. These forces do not require direct physical contact between objects to interact.
What the different types of contact and non-contact forces?
Contact forces involve direct physical contact between objects, such as friction and normal force. Non-contact forces act at a distance without physical contact, such as gravity, electrostatic, and magnetic forces.
How are contact forces and non-contact forces alike?
Contact forces and non-contact forces are both types of interactions that can cause an object to accelerate or deform. The main similarity between them is that they both involve a force acting between two objects, but the key difference is that contact forces require physical contact between the objects, while non-contact forces can act at a distance without direct contact.
How will you differentiate contact from non-contact?
Contact forces involve direct physical interaction between objects, such as friction or tension, while non-contact forces act at a distance, such as gravity or magnetic force. Contact forces are mediators introducing reaction force and normal forces, whereas non-contact forces involve no physical touch between objects.
What is non-contact frce?
Non-contact forces are forces exerted on an object by another object which is not in contact with it, a good example being gravitational force.
What are the two groups forces and how are they different?
In physics, there are two main groups of forces: contact forces and non-contact forces. Contact forces require physical contact between two objects to occur, such as friction, tension, or normal forces. Non-contact forces, on the other hand, act at a distance and do not require direct contact, like gravity, electromagnetism, and nuclear forces.
Is electro static a contact or a non contact force?
Electrostatic forces work at a distance. Non contact.
What is the different between contact and non-contact forces?
contact forces are those types of forces which results when the two interacting objects are perceived to be physically contacting each other. while non-contact force is any force applied to an object(or body) by another body that has not indirect contact with each other....
Is static a contact force?
No, Stactic electricity is a non-contact force!
How are contact forces and noncontact forces alike and how are they different?
Contact forces and non-contact forces are alike in that they both involve interactions between objects that cause a change in motion. However, contact forces require direct physical contact between objects, such as friction and normal force, while non-contact forces, like gravity and magnetic force, act at a distance without physical contact.
