Types of Non-Contact Forces
They are further subdivided into the following forces:
Gravitational Force
Newton’s law of gravity says that “gravitational forces between two bodies are directly equal to the product of their masses and inversely proportional to the square of the distance between them.” Large things, such as planets and stars, exert this force.
Electrostatic Force
Electrostatic forces are the sorts of forces that all electrically charged bodies in the cosmos exert on other electrically charged substances. Based on the charge of the bodies, these forces can be both attractive and repulsive in nature.
Magnetic Force
Magnetic forces are the sorts of forces exerted by a magnet on magnetic objects. They exist in the absence of any physical interaction between two things.
Contact and Non Contact Forces
Contact and Non-Contact Forces are the two main types of forces. Contact Force is a force that acts between objects in contact with each other. For example, Contact force can be experienced when an object is sliding on a surface, due to frictional force. However, Non-Contact Force does not require any physical contact interaction. For example, when an apple falls down from a tree, because of gravitational force or pull, Some important examples of Contact Forces are Frictional Force, Air Drag (or resistance), Surface Tension, Buoyant Force, Applied Force, Normal Force, Muscular Force and so on. Similarly, some examples of Non-Contact Forces are Gravitational Force, Electrostatic Force, Magnetic Force, Nuclear force, etc.
