```									Newton’s Laws of Physics

Chapter 2, Section 1
I. Law of Gravitational Force
A. Gravity depends on
1) Mass (matter)
2) Distance
B. Weight the measure of the
gravitational force (measured in
Newtons)
C. Acceleration Due to Gravity
1) 10 m/s/s (10 m/s2)
2) Free Fall- gravity is the ONLY force
acting on an object.
3) Air Resistance (fluid friction)- the
force that slows falling objects ON
EARTH.
II. Newton’s First Law – Law of
Inertia
A. Inertia is the tendency of an
object to resist change in motion.
1) An object at rest wants to
stay at rest
2) An object in motion
wants to stay in motion
3) Unless acted upon by an
unbalanced force
III. Newton’s Second Law
A. force = mass x acceleration or
(f=m x a) or
1 newton of force =
1 kg mass x 1m/s2

B. Forces are measured in newtons.
V. Newton’s Third Law

A. for every action force, there
is an equal and opposite
reaction force.
II.   Definition of Inertia

A. the tendency of an object to resist
changes in motion.
B. the more mass, the more inertia an
object has.
