Newton's 2nd Law:
When the Net Force > 0
The acceleration of a body
depends directly on the net force acting on it and
indirectly on the body's mass
(m)

a 
=

F_{net} 
(N) 
(s^{2}) 
m 
(Kg) 
Inertia  an object's resistance to a change
in motion due to its mass
Mass and Inertia
are
directly related

Larger the Mass,
the Greater the Inertia
Inertia and Mass Directly
Related
Twice the Mass,
Twice the Inertia
(an object's resistance to being accelerated
by a force due to its mass)

"Why is it initially so
difficult to pedal a bike
when you start from
rest?"


"And why is it so easy
to pedal the bike once
you obtain
your desired
speed?"

Inertia  When you first
start pedaling you are
feeling the inertial of the bike and body.
(force required to change motion)
Once in motion you only
need to apply a
force
to offset friction

"Why are the most
massive (most inertia)
football
players
lineman?"


"Why are the least
massive (least inertia)
football
players
receivers?"


"Receivers want to
change motion,
lineman
want to hold
their
ground"
