speed
rate of change of an object in any direction
velocity
speed of something in a specific direction
acceleration
rate of change of velocity
force
mass X acceleration
acceleration
final velocity - initial velocity divided by the time
gravitational force
gravitation(6.67X10 to the -11 NM/kg^2)X mass 1 X mass 2 divided by distance squared
weight
mass X gravity
centripetal force
circular motion
freefall
fall to earth without air resistance
freefall
distance = 1/2 average acceleration X time squared
newtons 1st law
every object at rest will stay at rest/motion unless acted on by an outside force
newtons first law
inertia
newtons 2nd law
force=mass X acceleration
newtons 3rd law
equal and opposite reaction for every action
potential
stored energy
kenetic
movement energy
work
up/down not side to side
work
