Selina Concise ICSE Solutions For Class 8 Physics Chapter – 3 – Force and Pressure **For Notes and Videos on other subjects from your syllabus, Click here 👉  Class 8 Notes & Videos on All Subjects FORCE  : “Is the cause which changes the state of a body (rest or state of motion) or it changes the size or shape of a body”. Weight of a body → The force with which a body is attracted towards the centre of earth mg = force of gravity. A force does not change the mass of the body that is why mass of a body on earth and moon in same but weight → force exerted on body is different.  Force cannot be seen but it is felt. → represents force, length of arrow gives magnitude and arrow points the direction.  S.I. unit of force is Newton (N). Newton: “Is that much force, which when acting on a body of mass 1 kg produces in it (increases) a speed of 1 M s -1  in the direction of its motion. 1 kgf = 9.8 N = 10 N (nearly) RIGID body: “When a force is applie...
