Detailed explanation-1: -Gravity as well as electrostatic and magnetic attraction and repulsion provide real life examples of forces being exerted by one object on another without them being in contact with each other. Many children are aware of magnetism and have played with fridge magnets.
Detailed explanation-2: -What is Non-Contact Force? 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.
Detailed explanation-3: -Some of the examples of non-contact forces are: Gravitational force. Magnetic force. Electrostatics.
Detailed explanation-4: -Magnetic force is the force which can act on an object without making any contact with the objects. Example: Force exerted by a magnet on another magnet.
Detailed explanation-5: -A non-contact force is a force applied on an object by another body without being in direct contact with the object. Examples: Gravitational force. Electromagnetic force. Strong Nuclear force.
