Expected lecture section median for MidTerm1 is 46 out of 60. If it is less
than 46 (say for example 41) then there will be a shift of +5 points for
everyone including those who got 60 out of 60.

74 Conservation of Energy and Momentum
in Collisions
Momentum is conserved
in all collisions.
Collisions in which
kinetic energy is
conserved as well are
called elastic collisi
