average speed
average speed= distance/time

acceleration equation
acceleration=change of velocity/time
=final velocityinitial velocity/time
a=v_finalv_initial/t

average velocity
average velocity=final velocity+initial velocity/2
 _
 v = final v + initial v /2

distance equation
distance=1/2(acceleration)(time)^2

force equation
force=mass x acceleration
f=ma

weight equation
 weight=mass x acceleration due to gravity
 w=m(g)

momentum equation
momentum=mass x velocity
p=mv

change of momentum
change of momentum=force x time

centripetal acceleration equation
centripetal acceleration=velocity squared/radius of circle

centripedal force equation
centripetal force=(mass x velocity squared)/radius of circle
f=mv^2/r

gravitational force equation
gravitational force=constant x (onemass x another mass)/distance squared
f=g (m1m2)/d^2

work equation
work=force x distance
w=fd

power equation
power=work/time
p=w/t

gravitational potential energy equation
gravitational potential energy=weight x height
PE=mgh

kinetic energy equation
kinetic energy=1/2(mass)(velocity)^2
KE=1/2mv^2

acceleration due to final velocity
acceleration due to final velocity=square root of (2 x to gravity x height of fall)
final v=sqrt 2gh
