First Law of Motion

p {margin: 0; padding: 0;} First law of motion Every body continuous it's state of rest or states of uniform motion unless compeled by an if external unbalenced force. That means f=0 then acceleration is zero. inertia It is the inability of a body to change it's state. Types: i) inedia of rest now ii) inertia of motion iii) inertia of direction. inertia is the measure of mass. Momentum momentum is the product of mass and velocity. P=mv xunit= kgm/s Direction of momentum = direction of velocity
