(b) contact and non-contact forces.
Answers
a.. balance force= resultant of all forces is equal to the zero
b.. those kind of forces which act due to contact in other hand non contact forces do not require any physical contacts
balanced force is that force in which the object that is forced by u is balance for example a box in on the road and u apply force to change the place of that box is called balanced force
unbalanced force is tht force in which the force is applied by u is not balanced at all example a coin is on the string and u apply force on the coin to move the coin on string but we know that it is impossible to moving coin on string it is called unbalanced force
contact force is that when we apply force on a particular object is called contact forc
non contact force is that in which we apply force on object with some other obj is called non contact force
