Describe a situation
where you know the mechanical
energy was not conserved. That is,
you know that total energy at the
start is not the same as at the end.
Why do you think it was not
conserved?
If you are struggling to think of
something, imagine a scenario where
there's some energy in the system at
the start, but then 0 J of energy in
the system by the end. Or vice versa.
