3). Name the types of contact and nen-contact force and explain in one sentence each
type?
Answers
Answer:
Contact forces
Contact forces are forces that act between two objects that are physically touching each other. Examples of contact forces include:
Reaction force
An object at rest on a surface experiences reaction force. For example, a book on a table.
Tension
An object that is being stretched experiences a tension force. For example, a cable holding a ceiling lamp.
Friction
Two objects sliding past each other experience friction forces. For example, a box sliding down a slope.
Air resistance
An object moving through the air experiences air resistance. For example, a skydiver falling through the air.
Non-contact forces
Non-contact forces are forces that act between two objects that are not physically touching each other. Examples of non-contact forces include:
Magnetic force
A magnetic force is experienced by any magnetic material in a magnetic field.
Opposite magnetic poles (N - S or S - N) attract each other.
Electrostatic force
An electrostatic force is experienced by any charged particle in an electric field.
Opposite charges (+ and -) attract
Like charges (- and -, or + and +) repel:
Gravitational force
A gravitational force is experienced by any mass in a gravitational field.
Masses are attracted towards each other by gravitational force

I am giving u the pic....hope u will like it....
Explanation:
I am explaining electrostatic force:-
Is the force exerted by a charged body on another charged or uncharged body.For example:- After rubbing comb on hair if we bring it near same bits of paper it gets attracted by the comb. Due to rubbing comb become electrically charged and then it attracts the uncharged paper bits...
