Law of Inertia :- The law of inertia states that if the net external force es zero continous to remain body a a + body at rest at rest and th motion continous to move with "uncfoam velocity. This property is called initia Inertia of rest The tendency of a body to remain is a of rest is called the inertia of rest. is person standing standing is a A when bus falls backward the bus suddenly starts moving forward Inertia of motion The tendency of a body to of uniform motion in remain is in a straight called inertia of motion. a state straight line is thin moving bus stops suddenly, the sithmoving bus stops a Person sitting in falls forward. Inertia of direction The inability of a body to change by itself its direction of motion. dire chen. is called inertia of athen setting a bus takes a sharp turn, a inside the bus experiences. away from the centre of person eriences a force acting the curved path. NEWTON FIRST LAW OF MOTION :- " continous to be uniform motion on a en state of rest straight line unless compelled to change that state by an external unbalanced force or The first law of motion as, can be simply expressa the net external force on a body is Acceleration its acceleration is o. Acc hon. force zero only if on the body there is a can be net extemal Linear Momentum defined linear momentum of oas, cts mass and es denoted by (P) a body S and velocity
