Explanation:
Hello !
Contact force:-A contact force is any force that requires contact to occur. examples Applied force,
Normal force,
Frictional force,
Tension force,
Air resistance force,
Spring force.
Non-contact force:-is a force which acts on an object without coming physically in contact with it. types of non-contact forces are gravitational force, magnetic force, electrostatic and nuclear force.
frictional force:-is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
Normal reaction force:-A force acting perpendicular to two surfaces in contact with each other.
The tension force is defined as the force that is transmitted through a rope, string or wire when pulled by forces acting from opposite sides.
The force exerted by a spring on objects attached to its ends is proportional to the spring's change in length away from its equilibrium length and is always directed towards its equilibrium position. F = -kx. The proportional constant k is called the spring constant.
During the collision, each body exerts a force on the other. This force is called an impulsive force.
The gravitational force :-is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart.
The electrostatic force is also known as the Coulomb force or Coulomb interaction. It's the attractive or repulsive force between two electrically charged objects.
magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion.
