here your answer ✨
Explanation:
Contact force is a force that is applied by objects in contact with each other. The contact force acts on a point of direct contact between the two objects.
A non-contact force is a force applied to an object by another body that is not in direct contact with it. Non-contact forces come into play when objects do not have physical contact between them or when a force is applied without any interaction
Contact force occurs due to the contact between two different objects. Non-contact force occurs due to either attraction or repulsion between two objects such that there is no contact between these objects. ... The frictional force is an example of a contact force. Gravitational force is an example of a non-contact force.
non contact force example
An apple falling down from a tree is one of the best examples of non-contact force. Iron pins attracted in the presence of a magnet bar without any physical contact. Falling of raindrops on earth is also an example of non-contact force. The charging of the hair and attraction of paper bits towards it.
Contact force example
Reaction force. An object at rest on a surface experiences reaction force
Tension. An object that is being stretched experiences a tension force.
Friction. Two objects sliding past each other experience friction forces.
Air resistance
