It's my birthday this month.
And I have a little birthday wish.
It's not much. But you could make it happen.
I wish that all high school physics students
could work problems using three equations of constant acceleration,
namely:
v = u + a.t
v^2 = u^2 + 2.a.x
x = u.t + 1/2 a.t^2
AND
that they could work final temperatures of mixes of liquids or
solid and liquid using the relation:
mass1 x specific heat1 x rise in temperature =
mass2 x specific heat2 x fall in temperature
