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.
Answer:
Magnetism is an example of a non-contact or action-at-a-distance force. These are forces which can act on an object without being in physical contact with it. The force of gravity is another example. Thus, gravity will pull a raindrop down to Earth without any tangible physical link between the Earth and the drop.
