These are the Example
Gravity
Without gravity we would be floating in
space and just keep going up.
About gravity
The theory of gravity was discovered by Sir Isaac Newton when an apple fell from a tree
Gravity also makes things stay on the ground
and keeps the moon in orbit around the earth.
Magnetism attracts two magnets together or makes
them push each other apart.
Magnetic fields are invisible to the human eye.
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.
Two magnets are placed close to each other is also a non contact force
Electromagnetism is another example of non-contact forces
There are various examples from electrostatics showing the attraction of small materials towards an object.
When electric current is passed through iron converting it into an electromagnet, it attracts iron and particles towards it, thus, displaying non contact force properties.
