I want summary of chapter force …

Thank you

We have to know about force as it is a greater term for exam... Force is a push or pull on a body or an object....There must be an interaction between two body for force to act .Let take some examples like hitting ball in cricket,kicking ball in football, opening or closing the door, pushing a car,suppose some persons doing these activities then can you guess what are they doing,yes they are applying their force to do this...interaction is a kind of action in which one objects or body interacts with other for applying of force....with out interaction you cannot apply force on any thing...on the basis of interaction force can be characterised as contact and non contact force...contact force are those force which can be apply only by touching the objects and non contact is without touching.....we can take example all thing we are doing that are contact force because every time we are applying our force by touching and gravitional force or electrostatic force and magnetic force are non contact forces...you can write about electrostatic force in exam as:- Take two balloons ,two refills and a wollen cloth..rough them in wollen cloth and take two balloons closer two each other you can see that they are trying to repel with each other and if you take two refills closer to each other then also they will repel means they don't want to come together and finally if you take one refills and one ballon then they will attract with each other...atoms are two types Electrons=- Protons=+ By doing the experiment we can Know that like charges --,++ repel and unlike charges-+,+- attract And attraction or reputation is nothing but a force This force carried out by static charges is called electrostatic charges..... Take a magnet and and an iron nail keep together they will try to attract and if you move the first magnet about one orientation and keep another magnet close to it you can see that they will repel... Like electrostatic force as like charge and unlike charge magnetic force have poles as like poles and unlike poles... Poles are north and south poles... Above results like poles repel with each other and unlike poles attract with each other.This force carried out by magnet is called magnetic force Last is gravitational force and please threw a stone in the air,you can see that the stone is not going up that is coming down towards the earth and that force of pulling any objects towards it by the earth is called gravitational force . Support me by thanking........ Keep learning
