A non-contact force is any force applied to an object by another body that is not in direct contact with it
example:
A human body's weight is a non-contact force exerted by the Earth on their mass
a contact force is a force between two objects (or an object and a surface) that are in contact with each other.
example
An example of contact force commonly encountered in college-level physics is the force between two masses A and B which are lying next to each other and a force F
That simply means that it requires no contact between the objects to act.
it is a noncontact force because before two objects touch, the electical charge held in one of the objects will "jump" to the other object, causing a static shock
Conduction is the transfer of energy by contact while convection is the transfer when liquid particles move in a cyclic manner when it is heated.
When two layers of a liquid in contact with each other move at different speeds, there will be a force between them. See Wikipedia for details.
A sound field, an electrical field, a magnetic field, and a gravity field would all be examples of non-contact forces. But though their effects are 'non-contact' their presence may nevertheless be easily detected.

force can be classified as contact and noncontact
The contact force will keep the ball moving but as the ball goes farther the ball slows down that's were the non contact force comes in it makes the ball not in contact
None, if you meant "contract".
The major differences between high-contact and low-contact service systems: high-contact system-to receive the service, the customer must be part of the system. Low-contact system is when customers are not in contact with the any services while the service is performed.

We developed new rules and got better equipment for contact sports.
