Types Of Forces

Hello everyone,

Today i am going to talk about the Forces.

                                             Types of Forces

   1.) Contact force

             a) Tension (T)

             b) Normal reaction (N)

             c) Spring force(Fs)

             d) Friction

   2.) Non contact force

              a) Gravitational force

              b) Electrostatic force

              c) Magnetic force

   3.) Weak force

   4.) Nuclear force

NORMAL REACTION (N) :

It is always perpendicular to the surface, or perpendicular to the point of contact.

TENSION (T) - String / Rod / Chain : 

It acts away from the point. If we change the string tension will also change. If there is massless string , tension remains same until string remain same.

See you tomorrow

Goodbye!!
