How the world works
An inquiry into the natural world and its laws; the interaction between the natural world (physical and biological) and human societies; how humans use their understanding of scientific principles; the impact of scientific and technological advances on society and on the environment.
Central idea: The Laws of Motion Govern How We Interact With the World Around Us
newton's First Law of Motion
An object at rest stays at rest (Inertia) and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

newton's Second law of motion
Acceleration is produced when a force acts on a mass. The greater the mass of the object being accelerated, the greater the amount of force needed to accelerate the object. (F = mass x acceleration)

newton's third law of motion
For every action, there is an equal and opposite reaction.
