Newton's Second Law of Motion and Physics

The principle that states that a mass acted on by a force undergoes acceleration in the direction of the force, with a magnitude inversely proportional to the mass and proportional to the force is called  Newton's 2nd Law of Motion.

According to Newton's 2nd Law a force that is applied to a mass produces a steady increase in speed. Also decreasing the mass and increasing the force produces a faster increase in speed, while increasing the mass and decreasing the force produces a slower increase in speed.

Every change in motion in the Universe is based on Newton's 2nd Law including both changes in speed and direction. It is indeed fundamental to understanding of motion since without it changes in motion can not be properly understood.
