First law of motion, Newton (Newton's first law of motion) or the law of inertia. "The object is to preserve the stationary or mobile environment consistently in a straight line. In addition to a force which is not a zero action "[6] is. If the object is stationary, it remains still intact. And if the moving object will move in a straight line. Fixed speed Or acceleration is zero The first case referred to Objects in static equilibrium (static equilibrium) and the latter is called. Kinetic objects in equilibrium (kinetic equilibrium) [7] The equation is as follows ΣF = 0 F is the total force exerted on the object.
