density equation
density = mass/volume
p=m/v
average speed
average speed= distance/time
_
v =d/t
acceleration equation
acceleration=change of velocity/time
=final velocity-initial velocity/time
a=v_final-v_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
