Newton’s First Law

X

Each object will remain in a state (speed = 0) ormoving along a straight line at constant speed (movingstraight uniform) unless he influenced force to changethe situation.

each object has inertia properties of objects(inertial / lazy nature objects), which will cause it toremain stationary or moving at a fixed speed.

Law of inertia

For stationary or moving objects straight uniform

F = 0

Newton’s First Law Of motion

As long as there is no resultant force acting on an object, the object will always be the case, ie stationary objects will always be silent and moving objects will move with constant velocity.

Contoh

A beam moving on an inclined plane. Based on Newton's second law, the acceleration of the beam can be determined with the following equation:ΣF = maw sin θ = mamg sin θ = mathus the acceleration beam on an inclined plane with slope θ is:a = g sin θwith g is the gravitational acceleration of 9.8 m / s

Summary Of this Matterial

Newton's law 'An object will keep moving with constant velocity unless the object work force unbalanced

Newton's Second Law "acceleration of an object is directly proportional to the magnitude of the force acting on the object and inversely proportional to the mass of the object '

Newton's Third Law 'if I do a style object on the second object, the second object will do a force equal to the first object in the opposite direction to the direction of the force penyebabbnya
