```Forces of matter
Newton's first law: the law of inertia
• Inertia states that an object at rest will stay
at rest until a force acts on it and an object
in motion will stay in motion until a force
acts on it.
Newton's second law: The law of
Acceleration
• Newton's second law states that the acceleration of an
object increases with increased force and decreased
with increased mass.
• The acceleration of a body is parallel and directly
proportional to the net force F and inverse to the mass.
The two people are pushing with the same power so
they don't move.
Newton's third law: action reaction
law
• Newton's third law states that for every
action there is an equal and opposite
reaction.
• The mutual forces of action and reaction between two
bodies are equal, opposite and collinear.
