Forces
First Law
inertia
before launch: forces cancel out
no movement
net force
zero
object does not move
any number
object moves
Second Law
acceleration of an object
net force divided by object's mass
acceleration does not change
smaller mass for greater acceleration
Third Law
one object exerts a force
second object exerts an equal force
force opposite to that of first
rocket launches with x newtons
x newtons also push against launcher

Work
formula
a transfer of energy
when applied force
moves an object
Energy
potential
stored energy
coiled spring
energy caused by position
kinetic
energy of motion
a flying bird
depends on
mass
speed
mechanical
kinetic energy
together
potential energy
t
formula
capacity or power to do work
work is an action on an object that displaces the object
